At a glance
CVE-2023-0550 is a high-severity Authorization Bypass Through User-Controlled Key vulnerability in the Quick Restaurant Menu WordPress plugin, affecting versions <= 2.0.2. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high integrity, availability impact). The issue is fixed in version 2.1.0; sites on affected versions should update now. Disclosed January 2023, reported by Marco Wotschka.
Vulnerability Overview
The Quick Restaurant Menu plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 2.0.2. This is due to the fact that during menu item deletion/modification, the plugin does not verify that the post ID provided to the AJAX action is indeed a menu item. This makes it possible for authenticated attackers, with subscriber-level access or higher, to modify or delete arbitrary posts.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on integrity, availability.
CWE-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in Quick Restaurant Menu <= 2.0.2 takes a caller who can reach the endpoint. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Quick Restaurant Menu the fix is 2.1.0: builds <= 2.0.2 are affected, anything from 2.1.0 onward is not.
Remediation
Update to version 2.1.0, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Quick Restaurant Menu 2.1.0 closes this, and updating the plugin is the step that ends it.
