Technical details
A privilege escalation vulnerability exists in the `user/add` API endpoint of phpMyFAQ due to an improper authorization check. While other user-management endpoints (like `editUser`) were previously hardened to ensure only SuperAdmins can grant SuperAdmin status, the `addUser` method in `UserController.php` lacks this guard. An attacker with delegated `USER_ADD/EDIT/DELETE` permissions can send a POST request to `/admin/api/user/add` with the `isSuperAdmin` parameter set to true. This allows the creation of a new account with full administrative privileges and attacker-controlled credentials, leading to a complete instance takeover. The issue is fixed in version 4.1.5.
