Technical details

The edit_message handler in MessageSystemController.php fails to validate that the authenticated user owns the message before allowing modifications. An authenticated attacker can update arbitrary system inbox messages, including the is_del column (to delete), look column (to mark as read), and uid column (to reassign). The vulnerability requires authentication but allows lateral privilege escalation within the system by tampering with other users' notifications. No authorization check is performed between the requesting user and the message owner.
