Name of the Vulnerable Software and Affected Versions MultiVendorX plugin for WordPress versions up to, and including, 3.5.7

Description The issue is related to Cross-Site Request Forgery due to missing or incorrect nonce validation on the submit comment() function. This allows unauthenticated attackers to submit comments via a forged request if they can trick a site administrator into performing an action such as clicking on a link.

Recommendations For versions up to, and including, 3.5.7, update to a version that includes proper nonce validation for the submit comment() function to prevent Cross-Site Request Forgery attacks. As a temporary workaround, consider restricting access to the comment submission functionality until a patch is available.
