What is CVE-2026-11818?
CVE-2026-11818 is a medium-severity missing authorization vulnerability in arraytics WPCafe – Restaurant Menu, Online Food Ordering & Table Booking System, published on 10 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The WPCafe – Restaurant Menu, Online Food Ordering & Table Booking System plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.0.14. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to list, create, update, delete, clone, and bulk-delete notification flow workflows that are intended to be managed only by administrators. The only protection on these endpoints is a wp_rest nonce check, which is obtainable by any logged-in user from the frontend page source.
