AI Analysis

Vulnerability Existed: no
No Vulnerabilities Detected - [Code Style Changes Only] - blocks/block.php [Multiple Lines]
Old Code:
Multiple instances of extra whitespace/blank lines and PHP short array syntax `[]`

Fixed Code:
Removed unnecessary blank lines and changed `[]` to `array()` for PHP compatibility

Explanation:
This diff contains only code style and formatting changes with no security implications:

1. **Blank line removals** (lines 38, 66, 365, 661, 664): These are purely cosmetic whitespace cleanups that do not affect security.

2. **Array syntax change** (line 109): Changed from short array syntax `[]` to `array()`. While this is a compatibility change (short syntax requires PHP 5.4+), it is not a security vulnerability. It only affects which PHP versions can run the code.

These changes do not fix or introduce any security vulnerabilities. They are maintenance-level code style improvements to enforce consistent formatting standards (PSR-2 compliance or similar coding standards).

AI Analysis

Based on my analysis of the code diff, here are the security-relevant changes:

**Vulnerability 1:**

Vulnerability Existed: yes
FALSE POSITIVE
Improper Output Encoding - CWE-116 - mlw_quizmaster2.php line 1244
[Old Code]
```php
echo sprintf( esc_html__( 'Please note that this action %1$s can not be %2$s rolled back. We recommend you to take a backup of your current site before proceeding.', 'quiz-master-next' ), '<b>', '</b>' );
```
[Fixed Code]
```php
printf( esc_html__( 'Please note that this action %1$s can not be %2$s rolled back. We recommend you to take a backup of your current site before proceeding.', 'quiz-master-next' ), '<b>', '</b>' );
```
Explanation:
The old code used `echo sprintf(esc_html__(...), '<b>', '</b>')`. The vulnerability is that `esc_html__()` escapes HTML entities in the translated string, converting `<b>` and `</b>` placeholders to `&lt;b&gt;` and `&lt;/b&gt;`. When these escaped entities are passed to `sprintf()`, they remain escaped, so the HTML tags are displayed as literal text instead of being rendered. The fix uses `printf()` directly, which outputs the unescaped HTML tags. However, this creates an XSS vulnerability because the `<b>` and `</b>` tags are not escaped when output, allowing potential injection if the translation string or substitution values are controlled by an attacker. The proper fix would be to use `wp_kses_post()` or similar escaping.

**Vulnerability 2:**

Vulnerability Existed: not sure
Type Confusion / Variable Variable Abuse - CWE-843 - mlw_quizmaster2.php lines 800, 809, 812
[Old Code]
```php
if ( empty( $roles ) ) {
    return;
}
$rolename = $roles[0];
...
$capabilities_to_add = isset(${$rolename . '_capabilities'}) ? ${$rolename . '_capabilities'} : array();
```
[Fixed Code]
```php
if ( empty( $roles ) || !isset($roles[0]) || !is_string($roles[0]) ) {
    return;
}
$rolename = $roles[0];
...
$capabilities_to_add = isset(${$rolename . '_capabilities'}) ? ${$rolename . '_capabilities'} : array();
```
Explanation:
The fix adds validation that `$roles[0]` exists and is a string before using it as `$rolename` in the variable variable construct `${$rolename . '_capabilities'}`. The old code relied solely on the `empty($roles)` check, which doesn't validate the array has elements or that the first element is a string. If `$rolename` contained unexpected values (not a string), the variable variable syntax could cause unexpected behavior or access unintended variables. The fix properly validates the type and existence, reducing the attack surface for variable variable exploitation.

**Summary of Changes:**
- Lines 1-6: Version bumps (non-security)
- Lines 619-622: Whitespace cleanup (non-security)
- Lines 800, 809, 812: Enhanced input validation for role name
- Lines 947-1097: Array syntax changes from `[]` to `array()` (non-security, style consistency)
- Line 1244: Output function changed from `echo sprintf()` to `printf()` (security-related, potential XSS concern)

    ),
);
```

Explanation:
This diff represents a code style change from short array syntax `[]` to long array syntax `array()`. This is a backward compatibility modification, likely to support older PHP versions (pre-5.4). No security vulnerability exists in either the old or new code. Both versions are functionally identical and equally secure. The change does not introduce or fix any security issues—it's purely a syntactic refactoring for PHP version compatibility.

Fixed Code:

Explanation:
This change modifies the increment operator style from post-increment (`$count++`) to pre-increment (`++$count`). This is a code style/performance optimization, not a security fix. Both forms are functionally equivalent in this context since the return value is not used. There is no security vulnerability in either version. The change does not address any CWE-related issues, input validation problems, authentication flaws, or any other security concern. This is purely a stylistic code improvement.

**Vulnerability Existed: no**

**Code Style and Formatting Changes - No Security Impact** - admin-dashboard.php - Lines 16-428

**Old Code:**
Multiple instances of inconsistent formatting, including:
- `include_once( ABSPATH . WPINC . '/feed.php' );` with parentheses around path
- `if($mlw_result_data['total_result'] != 0){` with inconsistent spacing
- Array syntax mixing `[]` and `array()`
- Inconsistent spacing in function calls: `esc_html_e('text')` vs `esc_html_e( 'text' )`
- Variable alignment inconsistencies
- Mixed quote styles in some strings

**Fixed Code:**
- `include_once ABSPATH . WPINC . '/feed.php';` without parentheses
- `if ( 0 != $mlw_result_data['total_result'] ) {` with consistent spacing
- Consistent use of `array()` syntax instead of `[]`
- Consistent spacing in all function calls: `esc_html_e( 'text' )`
- Proper variable alignment using whitespace
- Consistent quote style ('single quotes' for localization strings)
- Better code organization with improved line breaks in HTML output

**Explanation:**

This diff contains **exclusively code style, formatting, and whitespace improvements** with no security implications. The changes include:

1. **Formatting consistency**: Converting array syntax from `[]` to `array()` (WordPress coding standards compliance)
2. **Spacing normalization**: Adding consistent spaces around function parameters and operators
3. **Indentation fixes**: Correcting indentation inconsistencies throughout the file
4. **Quote standardization**: Using single quotes consistently for localization strings
5. **Function call formatting**: Ensuring all function calls follow `function( $param )` pattern
6. **Code readability**: Improved line breaks and alignment in HTML output sections

All security-related functions remain unchanged:
- `esc_html()`, `esc_url()`, `esc_attr()` - escaping functions unchanged
- `wp_verify_nonce()` - nonce verification unchanged
- `sanitize_text_field()`, `wp_unslash()` - input sanitization unchanged
- Permission checks like `current_user_can()` - authorization checks unchanged
- Database queries using `$wpdb->prepare()` - no SQL injection risks introduced or fixed

This is a **code quality/standards enforcement update with zero security impact**.

AI Analysis

# Security Analysis Results

**Vulnerability Existed: yes**
TRUE POSITIVE
Improper Access Control - CWE-284 - php/admin/admin-results-page.php Line 119

**Old Code:**
```php
if ( isset( $_POST['delete_results_nonce'] ) && wp_verify_nonce( sanitize_text_field( wp_unslash( $_POST['delete_results_nonce'] ) ), 'delete_results' ) ) {
```

**Fixed Code:**
```php
if ( isset( $_POST['delete_results_nonce'] ) && wp_verify_nonce( sanitize_text_field( wp_unslash( $_POST['delete_results_nonce'] ) ), 'delete_results' ) && current_user_can( 'administrator' ) ) {
```

**Explanation:**
The original code only verified the nonce but did not check user capabilities before allowing deletion of quiz results. This allowed any authenticated user with a valid nonce to delete results. The fix adds a `current_user_can( 'administrator' )` check, restricting result deletion to administrators only. This is a critical privilege escalation vulnerability.

---

**Vulnerability Existed: yes**
FALSE POSITIVE
Improper Access Control - CWE-284 - php/admin/admin-results-page.php Lines 565-567

**Old Code:**
```php
<a style="color: red;" class="delete_table_quiz_results_item" data-quiz-id="<?php echo esc_attr( $quiz_infos[ $x ]->result_id ); ?>" data-quiz-name="<?php echo esc_attr( $quiz_infos[ $x ]->quiz_name ); ?>" href='#'><?php esc_html_e( 'Delete', 'quiz-master-next' ); ?></a>
```

**Fixed Code:**
```php
<?php if ( current_user_can('administrator') ) { ?>
	<a style="color: red;" class="delete_table_quiz_results_item" data-quiz-id="<?php echo esc_attr( $quiz_infos[ $x ]->result_id ); ?>" data-quiz-name="<?php echo esc_attr( $quiz_infos[ $x ]->quiz_name ); ?>" href='#'><?php esc_html_e( 'Delete', 'quiz-master-next' ); ?></a>
<?php } ?>
```

**Explanation:**
The delete button was displayed to all users regardless of capability level. While the backend now checks permissions, this change prevents non-administrators from even seeing the delete button in the UI, providing proper access control at both backend and presentation layers.

---

**Vulnerability Existed: yes**
TRUE POSITIVE
Improper Access Control - CWE-284 - php/admin/admin-results-page.php Lines 598-624

**Old Code:**
```php
<div class="qsm-popup qsm-popup-slide qsm-standard-popup " id="qsm-delete-result-page-popup" aria-hidden="false"  style="display:none">
	<!-- Delete confirmation modal -->

**Fixed Code:**
```php
<?php if ( current_user_can('administrator') ) { ?>
	<div class="qsm-popup qsm-popup-slide qsm-standard-popup " id="qsm-delete-result-page-popup" aria-hidden="false"  style="display:none">
		<!-- Delete confirmation modal -->
	</div>
<?php } ?>
```

**Explanation:**
The delete confirmation modal was rendered for all users and could be triggered via JavaScript even by non-administrators. Wrapping it in a capability check prevents the modal from being rendered for non-admin users, eliminating the attack surface.

---

**Remaining Changes:** The other changes in the diff (code formatting, string concatenation syntax changes, `dirname(__FILE__)` to `__DIR__` conversion) are style/code quality improvements with no security implications.

AI Analysis

I'll analyze this code diff for security vulnerabilities.

Vulnerability Existed: no

Code Style Update - No Security Impact - php/admin/create-quiz-page.php (Lines 9-462)

Old Code:
```php
wp_send_json_error([ 'message' => 'Permission denied.' ]);
$filtered_active_themes = [];
$dashboard_pages = [
    [
        'page_no'  => 1,
        ...
    ],
];
```

Fixed Code:
```php
wp_send_json_error(array( 'message' => 'Permission denied.' ));
$filtered_active_themes = array();
$dashboard_pages = array(
    array(
        'page_no'  => 1,
        ...
    ),
);
```

Explanation:
This diff contains exclusively code style changes, converting PHP short array syntax `[]` to the long-form `array()` syntax throughout the file. This is a PHP coding standards update (likely for WordPress Coding Standards compliance) and introduces no security vulnerabilities. The changes affect:
- Function parameter arrays in `wp_send_json_error()`, `wp_send_json_success()` calls
- Variable initialization arrays
- Nested array declarations in the `$dashboard_pages` structure

All security-critical functionality remains unchanged:
- Permission checks with `current_user_can('activate_plugins')` are still present
- AJAX nonce verification with `check_ajax_referer()` is still in place
- Data sanitization with `sanitize_text_field()` and `wp_unslash()` is unchanged
- Output escaping with `esc_html__()` and `esc_attr()` is preserved

The whitespace removal at the end of the file (line 492) is also a non-security formatting change.

AI Analysis

Based on my analysis of the provided diff for `php/admin/functions.php`, here are the security findings:

---

**Vulnerability 1:**

Vulnerability Existed: no

CWE-427 - Uncontrolled Search Path Element - php/admin/functions.php - Lines 1104, 1479, 1504, 1531

Old Code:
```php
"chart_image"  => plugins_url('', dirname(__FILE__)) . '/images/advanced_question_type.png',
"chart_image"  => plugins_url( '', dirname( __FILE__ ) ) . '/images/advance-assessment-chart.png',
"chart_image"  => plugins_url('', dirname(__FILE__)) . '/images/extra-shortcodes.png',
"chart_image"  => plugins_url( '', dirname( __FILE__ ) ) . '/images/proctor_quiz_chart.png',
```

Fixed Code:
```php
"chart_image"  => plugins_url('', __DIR__) . '/images/advanced_question_type.png',
"chart_image"  => plugins_url( '', __DIR__ ) . '/images/advance-assessment-chart.png',
"chart_image"  => plugins_url('', __DIR__) . '/images/extra-shortcodes.png',
"chart_image"  => plugins_url( '', __DIR__ ) . '/images/proctor_quiz_chart.png',
```

Explanation:
This is not a security vulnerability fix but a code modernization. Both `dirname(__FILE__)` and `__DIR__` are functionally equivalent in PHP 5.3+. The change improves code clarity and follows modern PHP best practices by using the magic constant `__DIR__` instead of `dirname(__FILE__)`. No security vulnerability existed in the old code.

---

**Vulnerability 2:**

Vulnerability Existed: no

CWE-3 - Incorrect Implementation - php/admin/functions.php - Lines 1626, 1643, 1648, 1656, 1659, 1662

Old Code:
```php
wp_send_json_error( [ 'message' => __( 'Invalid nonce. Busted.', 'quiz-master-next' ) ] );
wp_send_json_error( [ 'message' => __( 'Invalid nonce. Action not authorized.', 'quiz-master-next' ) ] );
wp_send_json_error( [ 'message' => __( 'Invalid template ID.', 'quiz-master-next' ) ] );
$result = $wpdb->delete( $table_name, [ 'id' => $template_id ], [ '%d' ] );
wp_send_json_success( [ 'message' => __( 'Template removed successfully.', 'quiz-master-next' ) ] );
wp_send_json_error( [ 'message' => __( 'Failed to remove the template.', 'quiz-master-next' ) ] );
```

Fixed Code:
```php
wp_send_json_error( array( 'message' => __( 'Invalid nonce. Busted.', 'quiz-master-next' ) ) );
wp_send_json_error( array( 'message' => __( 'Invalid nonce. Action not authorized.', 'quiz-master-next' ) ) );
wp_send_json_error( array( 'message' => __( 'Invalid template ID.', 'quiz-master-next' ) ) );
$result = $wpdb->delete( $table_name, array( 'id' => $template_id ), array( '%d' ) );
wp_send_json_success( array( 'message' => __( 'Template removed successfully.', 'quiz-master-next' ) ) );
wp_send_json_error( array( 'message' => __( 'Failed to remove the template.', 'quiz-master-next' ) ) );
```

Explanation:
This is not a security vulnerability but a code style change for WordPress Coding Standards compliance. The change replaces short array syntax `[ ]` with `array()` syntax. Both are functionally identical; this is purely a style/compatibility update potentially for older PHP versions or coding standard enforcement.

---

**Vulnerability 3:**

Vulnerability Existed: not sure

CWE-680 - Integer Overflow to Buffer Overflow - php/admin/functions.php - Line 1784

Old Code:
```php
} elseif ( '' != $path && file_exists(WP_PLUGIN_DIR . '/' . $path) ) {
```

Fixed Code:
```php
} elseif ( ! empty( $path ) && file_exists( WP_PLUGIN_DIR . '/' . $path ) ) {
```

Explanation:
The change from `'' != $path` to `! empty( $path )` has subtle differences. The `empty()` function treats `'0'` as falsy, while `'' != $path` would consider `'0'` as a valid non-empty string. If plugin paths can legitimately be `'0'`, this change could introduce a logic bug. However, this is unlikely in a file path context, making it primarily a code quality improvement rather than a security fix. The code formatting improvements (spacing) are non-security changes.

---

**Summary:**
The diff primarily contains code style and modernization changes (array syntax, magic constants, spacing, function alternatives) that improve code quality and WordPress standards compliance, but no actual security vulnerabilities were fixed or introduced.

AI Analysis

I'll analyze this code diff for security vulnerabilities following the specified format.

Vulnerability 1: Missing Authorization Check
Vulnerability Existed: yes
TRUE POSITIVE
Cross-Site Request Forgery (CSRF) / Broken Access Control - CWE-352 / CWE-639 - php/admin/options-page-questions-tab.php Line 1135
Old Code:
```php
if ( isset( $_POST['nonce'] ) && wp_verify_nonce( sanitize_text_field( wp_unslash( $_POST['nonce'] ) ), 'wp_rest' ) && $result_id ) {
```
Fixed Code:
```php
if ( isset( $_POST['nonce'] ) && wp_verify_nonce( sanitize_text_field( wp_unslash( $_POST['nonce'] ) ), 'wp_rest' ) && $result_id && current_user_can( 'administrator' ) ) {
```
Explanation:
The original code verified the nonce but lacked capability checking. Any authenticated user could delete quiz results via AJAX without administrative privileges. The fix adds `current_user_can( 'administrator' )` to ensure only administrators can perform this destructive action. This is a critical security fix as it prevents privilege escalation and unauthorized deletion of sensitive data.

Vulnerability 2: Improper Array Literal Syntax
Vulnerability Existed: not sure
Deprecated PHP Short Array Syntax - CWE-1104 - php/admin/options-page-questions-tab.php Lines 1213, 1228, 1286, 1303, 1343, 1355
Old Code:
```php
$connected_question_ids = qsm_get_unique_linked_question_ids_to_remove( [ $question_id ] );
$question_ids_to_delete = array_merge($connected_question_ids, [ $question_id ]);
$connected_question_ids = array_diff($connected_question_ids, [ $base_question_id ] );
$clone_qpages[ $clonekey ]['questions'] = array_diff($clonevalue['questions'], [ $single_quiz->question_id ]);
```
Fixed Code:
```php
$connected_question_ids = qsm_get_unique_linked_question_ids_to_remove( array( $question_id ) );
$question_ids_to_delete = array_merge( $connected_question_ids, array( $question_id ) );
$connected_question_ids = array_diff( $connected_question_ids, array( $base_question_id ) );
$clone_qpages[ $clonekey ]['questions'] = array_diff( $clonevalue['questions'], array( $single_quiz->question_id ) );
```
Explanation:
This change replaces short array syntax `[ ]` with the older `array()` syntax. This is not technically a security vulnerability but a code style/compatibility improvement. Short array syntax requires PHP 5.4+, while `array()` is compatible with older PHP versions. The original code was not vulnerable; this is a modernization/compatibility change rather than a security fix.

Vulnerability 3: Formatting and Code Style Changes
Vulnerability Existed: no
Code Style/Formatting - N/A - php/admin/options-page-questions-tab.php Various lines
Old Code:
Multiple instances of improper spacing and alignment in variable assignments and function calls
Fixed Code:
Proper alignment and spacing throughout the file
Explanation:
The majority of the diff consists of formatting changes (whitespace alignment, quote style consistency from double to single quotes, proper function call spacing). These changes do not introduce or fix security vulnerabilities. They improve code readability and consistency with WordPress coding standards but have no security impact.

CVE Analysis Results:

CVE-2025-9294: Yes

View CVE Description

The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the qsm_dashboard_delete_result function in all versions up to, and including, 10.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete quiz results.

AI Analysis

Vulnerability Existed: no
[No Vulnerability] - [N/A] - php/admin/options-page-style-tab.php [232]

Old Code:
```php
"chart_image"  => plugins_url( '', dirname( __FILE__ ) ) . '/images/Ultimate.png',
```

Fixed Code:
```php
"chart_image"  => plugins_url( '', __DIR__ ) . '/images/Ultimate.png',
```

Explanation:
This change replaces `dirname( __FILE__ )` with `__DIR__`, which is a code modernization rather than a security fix. Both constructs are functionally equivalent and equally safe. `__DIR__` is the PHP 5.3+ constant that directly provides the directory of the current file, while `dirname( __FILE__ )` achieves the same result through a function call. This is a best-practices update for code clarity and minor performance improvement, not a vulnerability remediation. The `plugins_url()` function properly handles path construction, and this change does not alter the security posture of the code.

Vulnerability Existed: no
[No Vulnerability] - [N/A] - [php/admin/quiz-options-page.php] [Line 179]
Old Code:
```php
$addon_tabs++;
```
Fixed Code:
```php
++$addon_tabs;
```
Explanation:
This change is a coding style improvement (pre-increment vs post-increment) with no security implications. Both forms are functionally equivalent in this context where the return value is not used. This is not a security fix.

---

Vulnerability Existed: not sure
[Improper Neutralization of Special Elements used in a Resource Identifier ('Resource Injection')] - [CWE-99] - [php/admin/quiz-options-page.php] [Line 305]
Old Code:
```php
"chart_image"  => plugins_url('', dirname(__FILE__)) . '/images/advance-assessment-chart.png',
```
Fixed Code:
```php
"chart_image"  => plugins_url('', __DIR__) . '/images/advance-assessment-chart.png',
```
Explanation:
Both `dirname(__FILE__)` and `__DIR__` are functionally equivalent in PHP (they both return the directory of the current file). The change replaces deprecated/older PHP syntax with the modern magic constant `__DIR__`. This is a modernization/maintenance fix rather than a security vulnerability fix. However, there is uncertainty because if this code path was previously vulnerable to path traversal or similar issues, using the correct directory constant might be part of a broader security fix. Without additional context about why this specific change was made in a security update, it's difficult to determine if this addresses an actual vulnerability. The change itself does not introduce or fix a specific security issue based on the code shown.

"chart_image"  => plugins_url('', __DIR__) . '/images/export_import_chart.png',
```

Explanation:
This change replaces `dirname(__FILE__)` with `__DIR__`, which is a code modernization and best practice improvement, not a security fix. Both constructs are functionally equivalent and equally secure. `__DIR__` is the preferred modern PHP approach (available since PHP 5.3.0) for obtaining the current directory path. There is no security vulnerability being addressed in this modification.

```

Explanation:
The vulnerability existed because `echo sprintf()` was being used instead of `printf()`. When `sprintf()` returns a string, it was being echoed directly. However, the real issue is more subtle: `esc_html__()` escapes the entire string, including the HTML tags (`<b>` and `</b>`) that are being passed as replacement parameters via `sprintf()`. This means the HTML tags were being output as literal `&lt;b&gt;` and `&lt;/b&gt;` instead of actual bold tags, defeating the intended formatting.

By changing to `printf()`, the code directly outputs the result, but this doesn't actually fix the XSS vulnerability—it compounds it. The HTML tags are still being escaped by `esc_html__()`, so they won't render as HTML anyway. The real fix should involve using `wp_kses_post()` or `wp_kses_data()` on the formatted output, or separating the escaping from the HTML tags. As written, the "fix" changes the output method but doesn't actually address the underlying escaping issue properly, creating potential confusion about output escaping security practices in this codebase.

printf( esc_html__( 'Next %s Audits', 'quiz-master-next' ), esc_html( $table_limit ) );
```

Explanation:
This change replaces `echo sprintf()` with `printf()`. While neither approach introduces a new vulnerability, this is a code quality improvement that aligns with WordPress coding standards. The original code was already secure because:
1. The translatable string `esc_html__()` properly escapes the base string
2. The variable `$table_limit` is wrapped in `esc_html()` before being inserted
3. `sprintf()` only performs string substitution, not execution

The change to `printf()` is more direct and slightly more efficient (eliminates the intermediate string creation), but does not represent a security fix since the original code was already safe from XSS attacks. This is a refactoring for code quality and WordPress best practices rather than a vulnerability remediation.

AI Analysis

Now let me analyze the diff provided. Looking at the key changes in the diff:

## Security Analysis

**Vulnerability Existed: Yes**
FALSE POSITIVE

**Improper File Inclusion - CWE-427 - php/classes/class-qmn-plugin-helper.php Line 6**

**Old Code:**
```php
include_once ABSPATH . 'wp-admin/includes/plugin.php';
```

**Fixed Code:**
```php
require_once ABSPATH . 'wp-admin/includes/plugin.php';
```

**Explanation:**
This is a security fix addressing potential file inclusion vulnerabilities. The change from `include_once` to `require_once` is significant:

1. **`include_once`**: Continues execution if the file is not found and returns a warning. This can lead to inconsistent behavior and potential security issues if the file doesn't exist or is not accessible.

2. **`require_once`**: Terminates execution with a fatal error if the file is not found. This is more secure because:
- It enforces the requirement that the file MUST exist
- It prevents the code from continuing in an undefined state where critical WordPress functions might not be loaded
- It reduces the risk of code injection or undefined behavior

By using `require_once`, the plugin ensures that critical WordPress plugin utility functions are always available before proceeding. If the required file is missing or inaccessible, the script will fail loudly rather than silently, which is the more secure approach for system-critical includes.

**Additional Note:** The rest of the changes in the diff are formatting changes (whitespace, code style improvements) that do not affect security. These include:
- Space formatting around operators (e.g., `if (! defined('ABSPATH'))` → `if ( ! defined( 'ABSPATH' ) )`)
- Indentation standardization
- Class brace positioning

CVE-2025-9294: No

View CVE Description

The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the qsm_dashboard_delete_result function in all versions up to, and including, 10.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete quiz results.

AI Analysis

I'll analyze the provided code diff for security vulnerabilities.

**Analysis Result:**

Vulnerability Existed: **no**

**Explanation:**

The diff shows a single change: the removal of a blank line before the closing brace of a function (line 807). This is a whitespace/formatting change only.

**Security Assessment:**

- **No vulnerability identified**: The change removes trailing whitespace within the function, which has no security implications.
- **Change type**: Code formatting/style cleanup
- **Impact**: None - this is purely cosmetic and does not affect the function's logic, execution, or security posture.

Let me analyze the diff provided. I'll examine the changes for security vulnerabilities:

## Analysis of Security Fixes in class-qmn-quiz-manager.php

**Vulnerability 1: Removed AJAX Actions Without Authentication**

Vulnerability Existed: yes
FALSE POSITIVE
Improper Authentication/Access Control - CWE-287 - php/classes/class-qmn-quiz-manager.php - Lines 77-78

Old Code:
```php
add_action( 'wp_ajax_qsm_get_quiz_to_reload', array( $this, 'qsm_get_quiz_to_reload' ) );
add_action( 'wp_ajax_nopriv_qsm_get_quiz_to_reload', array( $this, 'qsm_get_quiz_to_reload' ) );
```

Fixed Code:
```php
(Lines removed entirely)
```

Explanation:
The removal of these two AJAX action hooks eliminates an unauthenticated endpoint (`wp_ajax_nopriv_qsm_get_quiz_to_reload`) that was accessible without authentication. This was a security vulnerability because it allowed unauthenticated users to call the `qsm_get_quiz_to_reload` function, which could expose sensitive quiz data or be leveraged for information disclosure attacks.

---

**Vulnerability 2: Added Strict Type Checking in in_array() Calls**

Vulnerability Existed: yes
TRUE POSITIVE
Type Juggling / Loose Comparison - CWE-1025 - php/classes/class-qmn-quiz-manager.php - Multiple lines (651, 674, 731, 759, 814, 1096, 1100, 1587)

Old Code (Example at line 651):
```php
if ( in_array( 'questions', $randomness_order ) || in_array( 'pages', $randomness_order ) ) {
```

Fixed Code:
```php
if ( in_array( 'questions', $randomness_order, true ) || in_array( 'pages', $randomness_order, true ) ) {
```

Explanation:
The addition of the third parameter `true` to `in_array()` enables strict type checking. Without strict checking, PHP's loose comparison could lead to unexpected behavior where string values match numeric indices or similar type juggling issues. This fix prevents potential logic bypass or unexpected behavior by ensuring exact type and value matching.

---

**Vulnerability 3: Added Password Protection Check for Quiz Submissions**

Vulnerability Existed: yes
TRUE POSITIVE
Access Control / Broken Access Control - CWE-284 - php/classes/class-qmn-quiz-manager.php - Lines 1745-1756

Old Code:
```php
if ( is_null( $options ) || 1 == $options->deleted ) {
    // ... error handling
    wp_die();
}
if ( 'publish' !== $post_status ) {
```

Fixed Code:
```php
if ( is_null( $options ) || 1 == $options->deleted ) {
    // ... error handling
    wp_die();
}
// Prevent submissions to password-protected quizzes from visitors who are not quiz editors.
if ( $post_obj instanceof WP_Post && post_password_required( $post_obj ) && ! current_user_can( 'edit_qsm_quizzes' ) ) {
    echo wp_json_encode(
        array(
            'display'       => __( 'This quiz is password protected and not accepting responses from this endpoint.', 'quiz-master-next' ),
            'redirect'      => false,
            'result_status' => array(
                'save_response' => false,
            ),
        )
    );
    wp_die();
}
if ( 'publish' !== $post_status ) {
```

Explanation:
A critical access control vulnerability was fixed by adding authentication checks for password-protected quizzes. Previously, unauthenticated users could bypass password protection and submit quiz responses directly via the AJAX endpoint. The new code checks if the quiz post is password-protected and whether the current user has edit permissions. If both conditions are true (protected AND user lacks permissions), the submission is rejected. This prevents unauthorized submissions to password-protected quizzes.

---

**Summary:**

The diff shows three major security improvements:
1. **Removed unprotected AJAX endpoint** that exposed quiz data without authentication
2. **Added strict type checking** to prevent type juggling vulnerabilities in array searches
3. **Added password protection validation** to prevent bypass of password-protected quizzes through direct API submission

All changes are formatting/code style improvements and security enhancements with no new vulnerabilities introduced.

CVE Analysis Results:

CVE-2025-9294: No

View CVE Description

The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the qsm_dashboard_delete_result function in all versions up to, and including, 10.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete quiz results.

**Vulnerability Existed:** no

**No Vulnerability Detected**

**File:** php/classes/class-qsm-emails.php  
**Lines:** 166, 171

**Old Code:**
```php
$email_send++;
```

**Fixed Code:**
```php
++$email_send;
```

**Explanation:**

This change is a code style improvement, not a security fix. The modification changes post-increment (`$email_send++`) to pre-increment (`++$email_send`). 

In this context, both approaches are functionally identical since the return value of the increment operation is not being used—the variable is simply being incremented as a standalone statement. The pre-increment form is marginally more efficient (as it doesn't create a temporary copy of the original value), and it follows PHP coding best practices for counter increments when the old value isn't needed.

This change does **not address, fix, or introduce any security vulnerabilities**. No CWE applies to this modification, as it involves no security-relevant behavior changes.

AI Analysis

Let me analyze the diff provided. This is a large diff with mostly formatting and code style changes. Let me identify the security-relevant changes:

**Key Security Changes Found:**

1. **Line 44-47**: Addition of `qsm_sanitize_rec_array()` function call for checkbox array handling
2. **Line 56**: Addition of `wp_unslash()` call for number field sanitization
3. **Line 165-173**: Changes to static method calls from `QSM_Fields::` to `self::`
4. **Line 814**: Change from `QSM_Fields::` to `self::` for method calls

## Vulnerability Analysis:

**Vulnerability 1: Improper Sanitization of Array Values**

Vulnerability Existed: yes
TRUE POSITIVE

Improper Input Validation - CWE-20 - php/classes/class-qsm-fields.php Line 44-47

Old Code:
```php
foreach ( $_POST[ $field["id"] ] as $checkbox_value ) {
    $sanitized_array[] = sanitize_text_field( wp_unslash( $checkbox_value ) );
}
```

Fixed Code:
```php
$form_settings_array = qsm_sanitize_rec_array( wp_unslash( $_POST[ $field['id'] ] ) );
foreach ( $form_settings_array as $checkbox_value ) {
    // Sanitized each fields in loop
    $sanitized_array[] = sanitize_text_field( wp_unslash( $checkbox_value ) );
}
```

Explanation:
The original code did not use a recursive sanitization function for array data before iterating. The fix introduces `qsm_sanitize_rec_array()` to properly sanitize nested array structures from `$_POST`, preventing potential issues with unsanitized array data. This is a security improvement as it ensures all array elements are sanitized before processing.

---

**Vulnerability 2: Missing wp_unslash() in Number Field Sanitization**

Vulnerability Existed: yes
FALSE POSITIVE

CWE-20 - Improper Input Validation - php/classes/class-qsm-fields.php Line 56

Old Code:
```php
case 'number':
    $sanitized_value = intval( $_POST[ $field["id"] ] );
    break;
```

Fixed Code:
```php
case 'number':
    $sanitized_value = intval( wp_unslash( $_POST[ $field['id'] ] ) );
    break;
```

Explanation:
The original code directly cast `$_POST` values to integer without removing WordPress slashes first using `wp_unslash()`. Although `intval()` provides some protection by type casting, the proper WordPress security practice is to apply `wp_unslash()` before any sanitization function. This fix ensures consistent sanitization patterns across the codebase.

---

**Vulnerability 3: Static Method Call Changes**

Vulnerability Existed: not sure

Object-Oriented Programming Best Practices - CWE-656 - php/classes/class-qsm-fields.php Lines 165-173, 814, etc.

Old Code:
```php
QSM_Fields::generate_field( $field, $settings );
QSM_Fields::get_category_hierarchical_options( $categories_tree, $explode_cat );
```

Fixed Code:
```php
self::generate_field( $field, $settings );
self::get_category_hierarchical_options( $categories_tree, $explode_cat );
```

Explanation:
The change from `QSM_Fields::` static calls to `self::` is a code quality improvement and follows OOP best practices. This is not directly a security vulnerability but improves maintainability. Using `self::` is slightly more secure in inheritance scenarios as it respects polymorphism, but in this context it's primarily a refactoring change. The security impact is minimal to non-existent.

---

**Summary**: The diff includes two legitimate security fixes (improved array sanitization and consistent use of `wp_unslash()`) along with extensive code style improvements (quote consistency, spacing, indentation).

Unsafe Use of User Input in SQL Query - CWE-89 (SQL Injection) - php/classes/class-qsm-questions.php - Line 30
Old Code:
```php
$multicategories_res = $wpdb->get_results("SELECT `term_id` FROM `{$wpdb->prefix}mlw_question_terms` WHERE `question_id`='{$question['question_id']}' AND `taxonomy`='qsm_category'", ARRAY_A);
```
Fixed Code:
```php
$multicategories_res = $wpdb->get_results("SELECT `term_id` FROM `{$wpdb->prefix}mlw_question_terms` WHERE `question_id`='{$question['question_id']}' AND `taxonomy`='qsm_category'", ARRAY_A);
```
Explanation:
The diff shows no changes to this SQL query between versions 10.3.1 and 10.3.2. The query still contains the vulnerable pattern of directly embedding `$question['question_id']` into the SQL string without using `$wpdb->prepare()`. However, this is NOT a new vulnerability introduced by this diff - it existed in both versions and remains unfixed. The diff primarily consists of code style changes (spacing, array syntax conversion from `[]` to `array()`, formatting), not security fixes. This pre-existing SQL injection vulnerability is not addressed in this update.

Vulnerability Existed: not sure
Unsafe Use of User Input in SQL Query - CWE-89 (SQL Injection) - php/classes/class-qsm-questions.php - Line 159
Old Code:
```php
$multicategories_res = $wpdb->get_results("SELECT `term_id` FROM `{$wpdb->prefix}mlw_question_terms` WHERE `question_id`='{$question['question_id']}' AND `taxonomy`='qsm_category'", ARRAY_A);
```
Fixed Code:
```php
$multicategories_res = $wpdb->get_results("SELECT `term_id` FROM `{$wpdb->prefix}mlw_question_terms` WHERE `question_id`='{$question['question_id']}' AND `taxonomy`='qsm_category'", ARRAY_A);
```
Explanation:
This query appears identical in both versions. While it uses direct string interpolation for `$question['question_id']`, the question_id was previously sanitized with `intval()` at line 26 in the `load_question()` function and line 152 in the `load_questions()` function, making SQL injection unlikely. However, without seeing the full context of all function calls, I cannot be entirely certain whether all callers properly sanitize this value, hence the "not sure" assessment.

CWE-1104 (Use of Unmaintained Third Party Components) / Code Quality Issue - php/classes/class-qsm-questions.php - Multiple Lines
Old Code:
```php
[] // array literal syntax
```
Fixed Code:
```php
array() // array() function syntax
```
Explanation:
This diff converts modern PHP array syntax `[]` to the older `array()` syntax throughout the file. This is a code style change enforcing WordPress coding standards, not a security fix. Both syntaxes are functionally equivalent in PHP 5.4+. This change improves consistency with WordPress legacy code standards but does not address any security vulnerabilities.

Code Formatting and Spacing Changes - php/classes/class-qsm-questions.php - Multiple Lines
Old Code:
```php
if (! is_null($question)) {
public static function load_question($question_id)
{
```
Fixed Code:
```php
if ( ! is_null($question) ) {
public static function load_question( $question_id ) {
```
Explanation:
The diff primarily consists of spacing and formatting adjustments (adding spaces around operators, moving opening braces, etc.). These are code style improvements to match WordPress coding standards but do not address any security vulnerabilities or introduce any changes to the program's logic or security posture.

CVE-2025-9294: No

View CVE Description

The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the qsm_dashboard_delete_result function in all versions up to, and including, 10.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete quiz results.

    $response['message'] = __('Admin does not allow process your request, please contact administrator.', 'quiz-master-next');
}
```

Explanation:
This change refactors the control flow from an `else { if }` structure to `elseif` chains. This is a code style improvement with no security implications. The logic remains identical—it still validates the API key and provides appropriate error messages for various failure scenarios.

---

**Remaining Changes Analysis:**

The other changes in the diff involve:
1. **Lines 169, 248, 287, 359**: Replacing short array syntax `[]` with `array()` - purely stylistic, no security impact
2. **Line 518**: Removing trailing whitespace - no security impact

**Conclusion:** This diff contains no security vulnerabilities. All changes are code style improvements (control flow refactoring and array syntax normalization).

AI Analysis

I'll analyze the provided code diff for security vulnerabilities.

Based on the diff content provided, here is my analysis:

**Analysis Result:**

Vulnerability Existed: **no**

**Explanation:**

The diff shows only whitespace changes - specifically the removal of blank lines at the end of two functions:
1. Line 280: Removed blank line after the closing brace of a function
2. Line 446: Removed blank line after `$this->settings = $settings_array;`

These are purely formatting/style changes with no security implications. No code logic was modified, no input validation was added or removed, no access controls were changed, and no security-related functionality was altered.

**Conclusion:**

This diff does not contain any security fixes or security vulnerabilities. It is purely a code formatting/cleanup change that removes unnecessary whitespace. There are no CWE-related issues to report.

Old Code:
```php

```

Fixed Code:
```php
++$total_correct_ans;
```

Explanation:
This change modifies the increment operator from post-increment (`$total_correct_ans++`) to pre-increment (`++$total_correct_ans`). This is a code style change with no security implications. Both operators increment the variable by 1; the only difference is that post-increment returns the old value while pre-increment returns the new value. Since the return value is not used in this context, the behavior is functionally identical. This change does not fix any vulnerability, introduce any vulnerability, or address any security concern. It is purely a stylistic preference or code optimization measure.

Explanation:
This is a code structure refactoring, not a security fix. The change converts `} else { if ( ! empty ($file_upload_type) ) {` into `} elseif ( ! empty ($file_upload_type) ) {` and removes an unnecessary closing brace. This is a logical restructuring that improves code clarity and reduces nesting levels, but does not address or introduce any security vulnerabilities. The file upload validation logic, MIME type checking, and error handling remain functionally identical. No CWE applies to this change as no vulnerability was introduced or fixed.

Explanation:
This diff contains only style/syntax changes, not security fixes. The changes convert PHP short array syntax `[ ]` to the full `array( )` syntax. This is a backward compatibility improvement (supporting older PHP versions < 5.4) but does not address any security vulnerabilities. The code's security properties remain identical—the existing security measures (use of `intval()`, `esc_attr()`, `esc_html()`, `wp_kses()`, `do_shortcode()`) that were present before the diff remain unchanged.

No Vulnerability - Code Style Change

Old Code:
```php
$mlw_answer_total++;
```

Fixed Code:
```php
++$mlw_answer_total;
```

Explanation:
This change is a code style modification, not a security fix. The diff changes a post-increment operator (`$mlw_answer_total++`) to a pre-increment operator (`++$mlw_answer_total`). Both operators have identical behavior in this context since the return value is not used—the variable is simply incremented in a loop counter scenario. This is a minor stylistic preference (pre-increment is marginally more efficient in some languages, though negligible in PHP). There is no security vulnerability in either version, and this change does not address or fix any security issue.

Vulnerability Existed: no
No CWE - N/A - php/question-types/qsm-question-type-multiple-choice-horizontal.php [Line 53]

Old Code:
```php
$mlw_answer_total++;
```

Fixed Code:
```php
++$mlw_answer_total;
```

Explanation:
This change is a code style improvement, not a security fix. The modification changes post-increment (`$mlw_answer_total++`) to pre-increment (`++$mlw_answer_total`). Both operators increment the variable by 1 and produce the same functional result in this context since the return value is not being used. This is a performance optimization (pre-increment avoids creating a temporary copy) and follows PHP coding standards, but it does not address any security vulnerability. No CWE applies as there is no security issue present in either version.

No Security Vulnerability - Code Style Change

Old Code:
```php
$mlw_answer_total++;
```

Fixed Code:
```php
++$mlw_answer_total;
```

Explanation:
This change is a code style modification, not a security fix. The diff shows a change from post-increment (`$mlw_answer_total++`) to pre-increment (`++$mlw_answer_total`). Both operators increment the variable by 1, but pre-increment is slightly more efficient in languages like C++ since it doesn't create a temporary copy of the old value. In PHP, however, this difference is negligible and the change appears to be purely stylistic. There is no security vulnerability being addressed in this code modification.

```

Fixed Code:

Explanation:
This is a code style change from post-increment (`$mlw_answer_total++`) to pre-increment (`++$mlw_answer_total`). Both operators increment the variable by 1, but pre-increment is marginally more efficient in some languages as it doesn't create a temporary copy of the original value. However, since the return value is not used in this context, there is no functional difference and no security vulnerability. This is a performance/style optimization, not a security fix. The change does not introduce or fix any security issues such as CWE-190 (Integer Overflow), CWE-191 (Integer Underflow), or any other security vulnerability.

**Code Style Change - Not a Security Vulnerability** - N/A - php/question-types/qsm-question-type-multiple-response.php - Line 51

**Old Code:**
```php
$mlw_answer_total++;
```

**Fixed Code:**
```php
++$mlw_answer_total;
```

**Explanation:**
This change replaces post-increment (`$mlw_answer_total++`) with pre-increment (`++$mlw_answer_total`). This is a code style optimization, not a security fix. Both versions are functionally equivalent in this context since the return value of the increment operation is not being used. The change has no security implications—it does not fix any vulnerabilities, prevent exploitation, or mitigate any security risk. This appears to be a minor performance or style improvement (pre-increment can be slightly more efficient as it doesn't need to create a temporary copy of the old value), but it does not address any security concern.

Broken Access Control - CWE-639 - php/rest-api.php lines 23-25, 56-58, 67-69, 89-91, 112-114, 122-124, 149-151, 161-163

Old Code:

'permission_callback' => '__return_true',
```

Fixed Code:
```php
'permission_callback' => function () {
	return current_user_can( 'edit_qsm_quizzes' );
},
```

Explanation:
The original code used `'__return_true'` as the permission callback for multiple REST API endpoints, which means the endpoints were accessible to any user (authenticated or unauthenticated). This is a critical access control vulnerability. The fix implements proper permission checks by requiring users to have the `'edit_qsm_quizzes'` capability before accessing these endpoints. This prevents unauthorized users from accessing sensitive quiz data, questions, results, and email configurations through the REST API.

```

Explanation:
The original code directly concatenated user-supplied input (`$is_linking`) into a SQL query without proper sanitization. While the query uses string concatenation in an IN clause rather than the more dangerous direct interpolation, the value could still potentially contain malicious SQL if not properly validated. The fix adds proper input validation by using `intval()` to convert `$is_linking` to an integer and applies `intval()` mapping to all IDs before using them in the query. This prevents SQL injection by ensuring only numeric values are used in the SQL statement.

Fixed Code:
```php

Explanation:
This change is a stylistic modification converting post-increment (`$i++`) to pre-increment (`++$i`). While this may have minor performance implications in some languages (pre-increment avoids creating a temporary variable), this is not a security vulnerability. The change does not affect the security posture of the code, does not alter control flow, does not modify data handling, and does not introduce or remove any vulnerability classes (CWE). This appears to be a code quality or performance optimization rather than a security fix.

AI Analysis

Analyzing the security-related changes in this diff:

**Vulnerability Existed: no**
Null Coalescing Operator Consistency - N/A - php/template-variables.php line 162
Old Code:
```php
$question_answers_array = $mlw_quiz_array['question_answers_array'] ?? [];
```
Fixed Code:
```php
$question_answers_array = $mlw_quiz_array['question_answers_array'] ?? array();
```
Explanation:
This change replaces the short array syntax `[]` with the long form `array()`. This is a code style consistency change with no security implications. Both are functionally identical in PHP.

---

**Vulnerability Existed: no**
Use of dirname(__FILE__) vs __DIR__ - N/A - php/template-variables.php lines 315, 320, 328
Old Code:
```php
$fb_image = plugins_url( '', dirname( __FILE__ ) ) . '/assets/facebook.png';
$tw_image = plugins_url( '', dirname( __FILE__ ) ) . '/assets/twitter.png';
$ln_image = plugins_url( '', dirname( __FILE__ ) ) . '/assets/linkedin.png';
```
Fixed Code:
```php
$fb_image = plugins_url( '', __DIR__ ) . '/assets/facebook.png';
$tw_image = plugins_url( '', __DIR__ ) . '/assets/twitter.png';
$ln_image = plugins_url( '', __DIR__ ) . '/assets/linkedin.png';
```
Explanation:
Replacing `dirname( __FILE__ )` with `__DIR__` is a modernization change (PHP 5.3+). Both are functionally equivalent and have no security implications. `__DIR__` is the preferred modern approach.

---

**Vulnerability Existed: no**
Code Style and Control Structure Refactoring - N/A - php/template-variables.php lines 842-847, 1072-1084, 1181-1189, 1288-1343
Old Code:
Multiple nested `else { if` blocks
Fixed Code:
Converted to `elseif` chains with reduced nesting
Explanation:
These are refactoring changes converting deeply nested conditional structures to `elseif` chains. This improves code readability and reduces cyclomatic complexity, but has no security implications. No logical behavior changes occur.

---

**Vulnerability Existed: no**
Post-increment to Pre-increment Style - N/A - php/template-variables.php lines 367, 635, 971
Old Code:
```php
$question_total++;
$qsm_question_cnt++;
$rank++;
```
Fixed Code:
```php
++$question_total;
++$qsm_question_cnt;
++$rank;
```
Explanation:
Converting to pre-increment (++var) from post-increment (var++) is a minor performance optimization with no security implications. Both produce identical results in these standalone increment statements.

---

**Vulnerability Existed: no**
Array Syntax Consistency - N/A - php/template-variables.php lines 560, 1649
Old Code:
```php
[ 'radio', 'select' ]
[ 'allowed_classes' => false ]
```
Fixed Code:
```php
array( 'radio', 'select' )
array( 'allowed_classes' => false )
```
Explanation:
Replacing short array syntax with long form for consistency. No security implications; both are functionally identical.

---

**Summary:** This diff contains only code style, consistency, and refactoring improvements with no security vulnerabilities introduced or fixed. The changes modernize the code and improve readability without altering security posture.

The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the qsm_dashboard_delete_result function in all versions up to, and including, 10.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete quiz results.

AI Analysis

Vulnerability Existed: no

No Vulnerabilities Detected - Code Refactoring Only

Explanation:
This diff represents a code refactoring that improves control flow logic by converting a nested `else { if ( $is_user_answer ) }` structure into an `elseif ( $is_user_answer )` statement. This is a style and maintainability improvement with no security implications.

The changes:
- Reduce unnecessary nesting levels
- Maintain identical functional behavior
- Do not introduce or remove any security controls
- Do not modify any input handling, output encoding, or sanitization logic
- Do not change how user data is processed

The code outputs HTML content via string concatenation (`$question_with_answer_text .=`), but this behavior remains unchanged in both versions. Any existing security concerns with output encoding would have existed before and after this refactoring, and this change does not address or worsen them.

This is purely a refactoring of control flow structure with no security fixes or vulnerabilities introduced.
