Description

The Contact Form 7 Style plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 3.2.

This makes it possible for unauthenticated attackers to quick edit templates via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
