Technical details

This is an authorization bypass vulnerability in the Chapter Controller component (App/Admin/Controller/ChapterController.class.php). The root cause is that ChapterController and AdController extend ThinkPHP's base Controller class instead of the application's AuthController, which means the session and role-based access control (RBAC) checks performed in AuthController::_initialize() are never invoked. An unauthenticated remote attacker can access administrative endpoints via HTTP requests without any session cookie or credentials. The vulnerability enables listing, creating, modifying, deleting content, and uploading files. No authentication or special preconditions are required; a simple HTTP request to administrative URLs returns 200 (success) instead of the expected 302 redirect to login. The project maintainers were notified early but have not yet responded with a patch.
