Based on the provided code diff, I will analyze it for security fixes.
Analysis:
1. The diff shows an addition of a note about Dependency Injection (DI) support in ActiveRecord.
2. It adds documentation about overriding the `instantiate()` method to support DI using `Yii::createObject()`.
3. This appears to be documentation-only change in a Japanese language guide file.
4. No actual code changes to the framework itself are present in this diff.
Answer:
Vulnerability Existed: no
No vulnerability identified - N/A - docs/guide-ja/db-active-record.md Lines 650-660
[No old code was present at these lines]
[Added documentation note about DI support and instantiate() method override]
Explanation:
- This is a documentation update in a markdown file, not a code change
- The content appears to be adding explanatory text about how to enable DI support in ActiveRecord
- No security vulnerability is being fixed in this diff
- The change is purely informational/educational in nature

Yii інкапсулює сесії та кукі в об'єкти, що дає можливість звертатися до них в об'єктноорієнтованому стилі та забезпечує додаткову зручність в роботі.+++## Сесії <span id="sessions"></span>++За аналогією з [запитами](runtime-requests.md) та [відповідями](runtime-responses.md), до сесій можна отримати доступ через `session` [компонент додатка](structure-application-components.md), який за замовчуванням є екземпляром [[yii\web\Session]].+++### Відкриття та закриття сесії <span id="opening-closing-sessions"></span>++Відкрити та закрити сесію можна наступним чином:++```php+$session = Yii::$app->session;++// перевіряєм що сесія вже відкрита+if ($session->isActive) ...++// відкиваєм сесію+$session->open();++// закриваємо сесію+$session->close();++// знищуємо сесію і всі пов'язані з нею дані.+$session->destroy();+```++Можна викликати [[yii\web\Session::open()|open()]] і [[yii\web\Session::close()|close()]] багаторазово без виникнення помилок; всередині компонента всі методи перевіряють сесію на те, відкрита вона чи ні.+++### Доступ до даних сесії <span id="access-session-data"></span>++Отримати доступ до збережених в сесію даних можна наступним чином:++```php+$session = Yii::$app->session;++// отримання змінної з сесії. Наступні способи використання еквівалентні:+$language = $session->get('language');+$language = $session['language'];+$language = isset($_SESSION['language']) ? $_SESSION['language'] : null;++// запис змінної в сесію. Наступні способи використання еквівалентні:+$session->set('language', 'en-US');+$session['language'] = 'en-US';+$_SESSION['language'] = 'en-US';++// видалення змінної з сесії. Наступні способи використання еквівалентні:+$session->remove('language');+unset($session['language']);+unset($_SESSION['language']);++// перевірка на існування змінної в сесії. Наступні способи використання еквівалентні:+if ($session->has('language')) ...+if (isset($session['language'])) ...+if (isset($_SESSION['language'])) ...++// обхід усіх змінних у сесії. Наступні способи використання еквівалентні:+foreach ($session as $name => $value) ...+foreach ($_SESSION as $name => $value) ...+```++> Info: При отриманні даних з сесії через компонент `session`, сесія буде автоматично відкрита, якщо вона не була відкрита до цього. У цьому полягає відмінність від отримання даних з глобальної змінної `$_SESSION`, що вимагає обов'язкового виклику `session_start()`.++При роботі з сесійними даними, які є масивами, компонент `session` має обмеження, що забороняє пряму модифікацію окремих елементів масиву. Наприклад,++```php+$session = Yii::$app->session;++// наступний код НЕ БУДЕ працювати+$session['captcha']['number'] = 5;+$session['captcha']['lifetime'] = 3600;++// а цей буде:+$session['captcha'] = [+ 'number' => 5,+ 'lifetime' => 3600,+];++// цей код також буде працювати:+echo $session['captcha']['lifetime'];+```++Для вирішення цієї проблеми можна використовувати такі обхідні прийоми:++```php+$session = Yii::$app->session;++// пряме використання $_SESSION (переконайтеся, що Yii::$app->session->open() був викликаний)+$_SESSION['captcha']['number'] = 5;+$_SESSION['captcha']['lifetime'] = 3600;++// отримайте весь масив, модифікуйте і збережіть назад у сесію+$captcha = $session['captcha'];+$captcha['number'] = 5;+$captcha['lifetime'] = 3600;+$session['captcha'] = $captcha;++// використовуйте ArrayObject замість масиву+$session['captcha'] = new \ArrayObject;+...+$session['captcha']['number'] = 5;+$session['captcha']['lifetime'] = 3600;++// записуйте дані з ключами, які мають однаковий префікс+$session['captcha.number'] = 5;+$session['captcha.lifetime'] = 3600;+```++Для покращення продуктивності та читабельності коду рекомендується використовувати останній прийом. Іншими словами, замість того, щоб зберігати масив як одну змінну сесії, ми зберігаємо кожен елемент масиву як звичайну сесійну змінну зі спільним префіксом.+++### Користувацьке сховище для сесії <span id="custom-session-storage"></span>++За замовчуванням клас [[yii\web\Session]] зберігає дані сесії у вигляді файлів на сервері. Однак Yii надає ряд класів, які реалізують різні способи зберігання даних сесії:++* [[yii\web\DbSession]]: зберігає дані сесії в базі даних.+* [[yii\web\CacheSession]]: зберігання даних сесії в попередньо сконфігурованому компоненті кешу [кеш](caching-data.md#cache-components).+* [[yii\redis\Session]]: зберігання даних сесії в [redis](https://redis.io/).+* [[yii\mongodb\Session]]: зберігання сесії в [MongoDB](https://www.mongodb.com/).++Усі ці класи підтримують однаковий набір методів API. В результаті ви можете перемикатися між різними сховищами сесій без модифікації коду додатку.++> Note: Якщо ви хочете отримати дані з змінної `$_SESSION` при використанні користувацького сховища, ви повинні бути впевнені, що сесія вже стартувала [[yii\web\Session::open()]], оскільки обробники зберігання користувацьких сесій реєструються в цьому методі.++Щоб дізнатися, як налаштувати і використовувати ці компоненти, зверніться до документації по API. Нижче наведено приклад конфігурації [[yii\web\DbSession]] для використання бази даних для зберігання сесії:++```php+return [+ 'components' => [+ 'session' => [+ 'class' => 'yii\web\DbSession',+ // 'db' => 'mydb', // ID компонента для взаємодії з БД. По замовчуванню 'db'.+ // 'sessionTable' => 'my_session', // назва таблиці для даних сесії. По замовчуванню 'session'.+ ],+ ],+];+```++Також необхідно створити таблицю для зберігання даних сесії:++```sql+CREATE TABLE session+(+ id CHAR(40) NOT NULL PRIMARY KEY,+ expire INTEGER,+ data BLOB+)+```++де 'BLOB' відповідає типу даних вашої DBMS. Нижче наведені приклади відповідності типів BLOB у найбільш популярних DBMS:++- MySQL: LONGBLOB+- PostgreSQL: BYTEA+- MSSQL: BLOB++> Note: В залежності від налаштувань параметра `session.hash_function` у вашому php.ini, може знадобитися змінити довжину поля `id`. Наприклад, якщо `session.hash_function=sha256`, потрібно встановити довжину поля на 64 замість 40.++### Flash-повідомлення <span id="flash-data"></span>++Flash-повідомлення - це особливий тип даних у сесії, які встановлюються один раз під час запиту і доступні лише протягом наступного запиту, після чого вони автоматично видаляються. Такий спосіб зберігання інформації в сесії найчастіше використовується для реалізації повідомлень, які будуть відображені кінцевому користувачу один раз, наприклад, підтвердження про успішну відправку форми.++Встановити та отримати flash-повідомлення можна через компонент програми `session`. Наприклад:++```php+$session = Yii::$app->session;++// Запит #1+// встановлення flash-повідомлення з назвою "postDeleted"+$session->setFlash('postDeleted', 'Ви успішно видалили пост.');++// Запит #2+// відображення flash-повідомлення "postDeleted"+echo $session->getFlash('postDeleted');++// Запит #3+// змінна $result буде мати значення false, оскільки flash-повідомлення було автоматично видалено+$result = $session->hasFlash('postDeleted');+```++Оскільки flash-повідомлення зберігаються в сесії як звичайні дані, в них можна записувати довільну інформацію, і вона буде доступна лише в наступному запиті.++При виклику [[yii\web\Session::setFlash()]] відбувається перезаписування flash-повідомлень з таким же назвою. Для того, щоб додати нові дані до вже існуючого flash-повідомлення, необхідно викликати [[yii\web\Session::addFlash()]]. +Наприклад:++```php+$session = Yii::$app->session;++// Запит #1+// додати нове flash-повідомлення з назвою "alerts"+$session->addFlash('alerts', 'Ви успішно видалили пост.');+$session->addFlash('alerts', 'Ви успішно додали нового друга.');+$session->addFlash('alerts', 'Дякуємо.');++// Запит #2+// Змінна $alerts тепер містить масив flash-повідомлень з назвою "alerts"+$alerts = $session->getFlash('alerts');+```++> Note: Намагайтеся не використовувати [[yii\web\Session::setFlash()]] спільно з [[yii\web\Session::addFlash()]] для flash-повідомлень з однаковою назвою. Це пов'язано з тим, що останній метод автоматично перетворює збережені дані в масив, щоб мати можливість зберігати та додавати нові дані в flash-повідомлення з тією ж назвою. В результаті, при виклику [[yii\web\Session::getFlash()]] можна виявити, що повертається масив, тоді як очікувалася строка.++## Кукі <span id="cookies"></span>++Yii представляє кожну з cookie як об'єкт [[yii\web\Cookie]]. Обидва компоненти програми [[yii\web\Request]] і [[yii\web\Response]] +підтримують колекції кукі через своє властивість cookies. У першому випадку колекція кукі є їх представленням з HTTP-запиту, у другому — представляє кукі, які будуть відправлені користувачу.++### Читання кукі <span id="reading-cookies"></span>++Отримати кукі з поточного запиту можна наступним чином:++```php+// отримання колекції кукі (yii\web\CookieCollection) з компонента "request"+$cookies = Yii::$app->request->cookies;++// отримання кукі з назвою "language". Якщо кукі не існує, "en" буде повернуто як значення за замовчуванням.+$language = $cookies->getValue('language', 'en');++// альтернативний спосіб отримання кукі "language"+if (($cookie = $cookies->get('language')) !== null) {+ $language = $cookie->value;+}++// тепер змінну $cookies можна використовувати як масив+if (isset($cookies['language'])) {+ $language = $cookies['language']->value;+}++// перевірка на існування кукі "language"+if ($cookies->has('language')) ...+if (isset($cookies['language'])) ...+```+++### Відправка кукі <span id="sending-cookies"></span>++Відправити кукі кінцевому користувачу можна наступним чином:++```php+// отримання колекції (yii\web\CookieCollection) з компонента "response"+$cookies = Yii::$app->response->cookies;++// додавання нової кукі в HTTP-відповідь+$cookies->add(new \yii\web\Cookie([+ 'name' => 'language',+ 'value' => 'zh-CN',+]));++// видалення кукі...+$cookies->remove('language');+// ...що еквівалентно наступному:+unset($cookies['language']);+```++Крім властивостей [[yii\web\Cookie::name|name]] та [[yii\web\Cookie::value|value]], клас [[yii\web\Cookie]] також надає ряд властивостей для отримання інформації про куки: [[yii\web\Cookie::domain|domain]], [[yii\web\Cookie::expire|expire]]. Ці властивості можна сконфігурувати, а потім додати кукі в колекцію для HTTP-відповіді.++> Note: Для більшої безпеки значення властивості [[yii\web\Cookie::httpOnly]] за замовчуванням встановлено в `true`. Це зменшує ризики доступу до захищеної кукі на клієнтській стороні (якщо браузер підтримує таку можливість). Ви можете звернутися до [httpOnly wiki](https://owasp.org/www-community/HttpOnly) для додаткової інформації.++### Валідація кукі <span id="cookie-validation"></span>++Під час запису та читання куків через компоненти `request` та `response`, як буде показано в двох наступних підрозділах, фреймворк надає автоматичну валідацію, яка забезпечує захист кукі від модифікації на стороні клієнта. Це досягається завдяки підписанню кожної кукі секретним ключем, що дозволяє додатку розпізнавати кукі, які були модифіковані на клієнтській стороні. У такому випадку кукі НЕ БУДЕ доступна через властивість [[yii\web\Request::cookies|cookie collection]] компонента `request`.++> Note: Валідація кукі захищає тільки від їх модифікації. Якщо валідація не була пройдена, отримати доступ до кукі все ще можна через глобальну змінну `$_COOKIE`. Це пов'язано з тим, що додаткові пакети та бібліотеки можуть маніпулювати кукі без виклику валідації, яку забезпечує Yii.+++За замовчуванням валідація кукі увімкнена. Її можна вимкнути, встановивши властивість [[yii\web\Request::enableCookieValidation]] в `false`, однак ми настійливо не рекомендуємо цього робити.++> Note: Кукі, які безпосередньо читаються/пишуться через `$_COOKIE` та `setcookie()`, НЕ БУДУТЬ валідовуватися.++При використанні валідації кукі необхідно вказати значення властивості [[yii\web\Request::cookieValidationKey]], яке буде використано для генерації згаданого вище секретного ключа. Це можна зробити, налаштувавши компонент `request` у конфігурації додатка:++```php+return [+ 'components' => [+ 'request' => [+ 'cookieValidationKey' => 'fill in a secret key here',+ ],+ ],+];+```++> Note: Властивість [[yii\web\Request::cookieValidationKey|cookieValidationKey]] є секретним значенням і повинно бути відомо лише тим, кому ви довіряєте. Не розміщуйте цю інформацію в системі контролю версій.
I have analyzed the provided code diff. This appears to be a Ukrainian language translation of the Yii2 framework documentation about sessions and cookies. Since this is documentation content rather than actual code changes, I need to assess whether any security vulnerabilities existed in the documentation examples.
Looking at the content, I can identify one potential security concern in the cookie validation section:
```
Vulnerability Existed: yes
CWE-798: Use of Hard-coded Credentials - docs/guide-uk/runtime-sessions-cookies.md [Lines 273-279]
[Old Code]
return [
'components' => [
'request' => [
'cookieValidationKey' => 'fill in a secret key here',
],
],
];
[Fixed Code]
The documentation should emphasize using a unique, cryptographically secure random value for cookieValidationKey that is stored in a secure configuration file outside of version control, rather than a placeholder value.
```
Additionally, I notice another potential security issue:
```
Vulnerability Existed: yes
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor - docs/guide-uk/runtime-sessions-cookies.md [Lines 216-218]
[Old Code]
// тепер змінну $cookies можна використовувати як масив
if (isset($cookies['language'])) {
$language = $cookies['language']->value;
}
[Fixed Code]
The documentation should warn about directly accessing cookie values without proper validation, as this could expose the application to tampered cookie values that bypass the framework's validation mechanisms.
```
And one more issue:
```
Vulnerability Existed: not sure
CWE-472: External Control of Assumed-Immutable Web Parameter - docs/guide-uk/runtime-sessions-cookies.md [Lines 35-45]
[Old Code]
// отримання змінної з сесії. Наступні способи використання еквівалентні:
$language = $session->get('language');
$language = $session['language'];
$language = isset($_SESSION['language']) ? $_SESSION['language'] : null;
[Fixed Code]
The documentation should include warnings about properly validating and sanitizing session data, as session variables can be manipulated by attackers if not properly secured.
```
Note: Since this is documentation content, the vulnerabilities are in the examples and guidance provided, not in actual executable code. The security issues relate to poor practices being demonstrated in the documentation examples.

Based on the provided code diff, I will analyze it for security vulnerabilities. **Analysis:** The diff shows the addition of documentation for a new `ArrayHelper::flatten()` method. This is purely documentation content and does not contain any actual code changes to the framework's source code. The examples demonstrate how the method works but don't reveal any security vulnerabilities in the implementation itself. However, I'll analyze the documented behavior for potential security concerns: **Vulnerability 1:** ``` Vulnerability Existed: not sure CWE-1022 - Use of a Broken or Risky Cryptographic Algorithm? - docs/guide/helper-array.md (Documentation) Old Code: N/A (New documentation) Fixed Code: N/A (New documentation) ``` **Note:** The documentation mentions that when keys collide, the method will overwrite previous values. This could potentially lead to data loss or unexpected behavior in applications, but it's not a security vulnerability in the traditional sense. The documentation itself doesn't introduce vulnerabilities - it merely documents existing functionality. **Conclusion:** The diff contains only documentation additions with no actual code changes to analyze for security vulnerabilities. The documented functionality appears to be standard array flattening behavior without obvious security implications.

Note: The vulnerability appears to be related to widget class resolution that could be manipulated to bypass security controls (like CSRF token validation) by allowing an attacker to substitute widget classes at runtime. The fix ensures that the actual widget class used during creation is tracked and used during destruction, preventing class substitution attacks.

Note: This appears to be a new configuration file being added rather than a security fix. The file defines view resolution rules for Yii2 controllers. While path traversal vulnerabilities could potentially exist in view resolution, this specific diff doesn't show a fix for an existing vulnerability but rather introduces new configuration.

The file itself doesn't contain any security vulnerability fixes, but rather adds metadata configuration for static analysis or code generation tools. The configuration specifies that certain method arguments should have properties with "protected=false" and "private=false" attributes, which suggests this is related to code accessibility or analysis rather than security patching.

The file defines access control rules for various methods that handle dynamic property access (__get, __set, __isset, __unset) and attribute manipulation methods. While this appears to be a security enhancement that restricts access to protected/private properties, without seeing the original code that existed before this file was added, it's difficult to determine if there was a specific vulnerability being fixed. The configuration seems designed to prevent improper modification of object attributes, which could relate to mass assignment vulnerabilities or property injection issues.

Note: The actual code change is extremely minimal - only removing a blank line at the end of the file. This type of change typically doesn't represent a security vulnerability fix. However, since the context shows the removal occurs in a database schema class and involves object creation, I'm indicating "not sure" as there could be a subtle information disclosure issue related to error messages or stack traces that might be affected by file formatting, though this is highly unlikely.

This diff represents the addition of static analysis configuration metadata (Meta-Storm) that defines relationships between method arguments in the BaseArrayHelper class. It does not contain any functional code changes that would introduce or fix security vulnerabilities. The file appears to be providing type relationship information for development tools rather than modifying application behavior.

Based on my analysis of the provided code diff, I can identify the following:
Vulnerability Existed: not sure
Input Validation - CWE-20 - framework/helpers/html.meta-storm.xml (entire file)
[Old Code]
File did not exist previously
[Fixed Code]
Added XML configuration file defining allowed HTML tags and form input types
This appears to be a security enhancement that adds input validation rules for HTML helper methods in the Yii2 framework. The meta-storm.xml file defines:
1. A whitelist of allowed HTML tags for methods like `tag()`, `beginTag()`, and `endTag()`
2. Input validation rules for various form input methods (`activeTextInput`, `activePasswordInput`, etc.)
3. Property validation for model attributes used in form helpers
The security improvement prevents potential XSS attacks by restricting which HTML tags can be generated and validating form input types, but since this is adding new validation rather than fixing existing vulnerable code, I cannot definitively say a vulnerability existed without seeing the actual code changes in the HTML helper methods themselves.
Note: This appears to be a static analysis configuration file (likely for a tool like Psalm or PHPStan) rather than runtime code, so the actual security impact depends on how this configuration is used by the analysis tool.

This diff shows only the addition of a new MIME type mapping for 'jxl' (JPEG XL image format) to 'image/jxl'. This is a routine update to support a new file format and does not represent a security vulnerability fix. The change simply expands the MIME type database without modifying any security-related functionality.

**Analysis:**
This diff shows a simple syntax fix in a Bosnian language translation file. The change corrects a missing closing brace `}` in a pluralization message format. This is a localization fix rather than a security vulnerability. The correction ensures proper pluralization formatting in the Bosnian language, preventing potential display issues or formatting errors in time-related messages. No security vulnerability is addressed by this change.

Explanation: This diff shows only localization updates for Traditional Chinese (zh-TW) language translations. The changes involve adding proper Chinese translations for English phrases. There are no security vulnerabilities being fixed here - these are purely linguistic improvements to make the framework more accessible to Traditional Chinese speakers. The changes don't affect any security-related functionality, input validation, or output encoding mechanisms.

```
**Analysis:**
The diff shows only the addition of a new test method `testStrictError()`. This is a test case that verifies the behavior of the `ErrorException::getName()` method when handling `E_STRICT` error codes, particularly in PHP 8.4+ where `E_STRICT` has been removed. There are no security vulnerabilities being fixed here - this is purely adding test coverage for existing functionality. The test uses the `@` operator to suppress potential warnings about undefined constants, which is appropriate for test code.

While this doesn't directly fix a security vulnerability, it could be related to ensuring proper cache invalidation which might have security implications (CWE-200: Information Exposure through caching of sensitive data). However, without more context about the actual cache implementation being tested, this is marked as "not sure".

This diff shows changes to test code only, specifically updating enum constant references from uppercase `ACTIVE` to PascalCase `Active`. These are test case modifications that verify the framework's enum handling behavior, not security fixes in production code. The changes appear to be related to test maintenance or refactoring rather than addressing security vulnerabilities.

This appears to be a code style/consistency change rather than a security fix. The file is in the tests directory, which typically contains test code rather than production code, further reducing security implications.

Note: This is a test case addition rather than a security fix. The vulnerability being addressed is the potential exposure of sensitive information (passwords) in logs when using wildcard patterns in maskVars. The test verifies that the masking functionality correctly handles wildcard patterns to prevent sensitive data leakage.

**Note:** This diff shows changes to test expectations, not the actual validator code. The changes indicate that the FileValidator now properly validates empty files and returns appropriate error messages when uploads are required. This suggests a fix for potential security issues where empty or missing files might bypass validation, but without seeing the actual FileValidator implementation changes, we cannot definitively identify specific vulnerabilities.
