Description

The MultiVendorX plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.5.7. This is due to missing or incorrect nonce validation on the submit_comment() function. This makes it possible for unauthenticated attackers to submit comments via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
