WordPress · The Restaurant Menu – Food Ordering System – Table Reservation · CVE-2022-3776
**Name of the Vulnerable Software and Affected Versions**
The Restaurant Menu – Food Ordering System – Table Reservation plugin for WordPress versions up to, and including, 2.3.1
**Description**
The issue is due to missing or incorrect nonce validation on several functions called via AJAX actions, such as `forms action`, `set option`, and `chosen options`. This allows unauthenticated attackers to perform administrative actions, like modifying forms, by tricking a site administrator into performing an action, such as clicking on a link.
**Recommendations**
For versions up to, and including, 2.3.1, update to a version that includes proper nonce validation for AJAX actions to prevent Cross-Site Request Forgery attacks.
As a temporary workaround, consider restricting access to the AJAX endpoints related to `forms action`, `set option`, and `chosen options` to minimize the risk of exploitation.
