Technical details
Missing object-level authorization in the Users::form() controller method allows a Secondary Administrator (user_type=1, user_id≠1) to alter the Primary Administrator's (user_id=1) user_type field, downgrading it to Guest/read-only status. The vulnerability arises because form() only checks whether the editor is modifying their own account (is_self_edit), but applies no boundary guard preventing changes to user_id=1. An authenticated attacker with Secondary Administrator privileges can directly target user_id=1 through the user-management UI or HTTP request to perform the privilege escalation.
