Vulnerability Existed: yes
TRUE POSITIVE
Improper Access Control - CWE-284 - community-events.php - Lines 164
Old Code:
```php
if ( !wp_verify_nonce( $_GET['event_approval_nonce'], 'event_approval_nonce' ) ) {
exit;
}
```
Fixed Code:
```php
if ( !current_user_can( 'manage_options' ) || !wp_verify_nonce( $_GET['event_approval_nonce'], 'event_approval_nonce' ) ) {
exit;
}
```
Explanation:
The original code only validated a nonce without checking user permissions. This is a critical access control vulnerability (CWE-284). Any authenticated WordPress user could forge or guess the nonce and approve events, even if they lacked administrative privileges. The fix adds a `current_user_can( 'manage_options' )` check, ensuring only users with administrator capability can approve events. This follows WordPress security best practices by requiring both capability check AND nonce validation before processing sensitive operations.
The Community Events plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ajax_admin_event_approval() function in all versions up to, and including, 1.5.6. This makes it possible for unauthenticated attackers to approve arbitrary events via the 'eventlist' parameter.
