CVE-2023-0555
CWE-862Published: January 27, 2023· Updated: Jun 17, 2026
Official Description
The Quick Restaurant Menu plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on its AJAX actions in versions up to, and including, 2.0.2. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to invoke those actions intended for administrator use. Actions include menu item creation, update and deletion and other menu management functions. Since the plugin does not verify that a post ID passed to one of its AJAX actions belongs to a menu item, this can lead to arbitrary post deletion/alteration.
Technical Analysis
CVE-2023-0555 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.1.
