NewCVE-2026-111909 (opens in a new tab)How to fix?
Upgrade thorsten/phpmyfaq to version 4.1.9 or higher.
Overview
thorsten/phpmyfaq is a FAQ system for PHP and MySQL, PostgreSQL and other databases
Affected versions of this package are vulnerable to Missing Authorization via the deleteUser() API in src/phpMyFAQ/Controller/Administration/Api/UserController.php, where an authenticated non-superadmin user holding the delete_user permission can send a DELETE request to /admin/api/user/delete with a target superadmin's userId (any value other than 1) and successfully remove that superadmin account. The authorization check in deleteUser() verifies only whether the target ID is 1 and whether the current account is protected, but does not call $user->isSuperAdmin() as the sibling methods editUser() and updateUserRights() do. This allows a delegated user manager to eliminate superadmin accounts, causing loss of administrative access and accountability.
