CVE-2023-0555Network attack vector

Subscriber-level menu deletion via unchecked AJAX actions

Published Jan 27, 2023 · Updated Apr 8, 2026

Missing authorization in Quick Restaurant Menu 2.0.2 and earlier allows remote authenticated users to create, alter, or delete menu items via AJAX. The erm_delete_menu_item handler passes an attacker-supplied post_id to wp_delete_post without checking the caller's capability, and other management actions likewise omit capability checks. Subscriber access reaches these authenticated AJAX actions; altering or deleting non-menu posts additionally requires the separately tracked object-type validation flaw.
