CVE-2023-0550Network attack vector

Arbitrary post modification via unchecked object identifier

Published Jan 27, 2023 · Updated Apr 8, 2026

IDOR in Quick Restaurant Menu 2.0.2 and earlier allows remote authenticated users to modify or delete arbitrary WordPress posts. Its AJAX handlers accept a caller-supplied post ID for menu-item modification or deletion without confirming that the referenced post is a menu item. Subscriber-level access is sufficient, and successful exploitation can alter site content or permanently remove posts.
