CVE-2023-0554Network attack vector

Menu item modification via forged AJAX requests

Published Jan 27, 2023 · Updated Apr 8, 2026

Cross-site request forgery in Quick Restaurant Menu 2.0.2 and earlier allows remote attackers to update menu items through forged AJAX requests. AJAX handlers in includes/admin/ajax-functions.php process menu-item update requests without correctly validating a WordPress nonce before changing stored items. Exploitation requires a logged-in site administrator to follow a crafted link or otherwise submit the attacker's request, after which menu content can be altered.
