Description
The Fusion Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.11.1. This is due to missing or incorrect nonce validation on an unknown function. This makes it possible for unauthenticated attackers to modify elements using third-party access tokens via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
