Authorization Bypass Through User-Controlled Key
The Quick Restaurant Menu plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 2.0.2. This is due to the fact that during menu item deletion/modification, the plugin does not verify that the post ID provided to the AJAX action is indeed a menu item. This makes it possible for authenticated attackers, with subscriber-level access or higher, to modify or delete arbitrary posts.
