Technical details

A missing authorization check in the deleteUser() API endpoint (DELETE /admin/api/user/delete) fails to verify whether the target user is a superadmin before deletion. An authenticated non-superadmin user with the delete_user permission can exploit this by sending a DELETE request with a superadmin's userId to completely remove that account from the system. The vulnerability exists in src/phpMyFAQ/Controller/Administration/Api/UserController.php and affects versions before 4.1.9.
