What the vulnerability does
01Description
The Fast & Fancy Filter – 3F plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.2.2. This is due to missing nonce verification in the saveFields() function, which handles the fff_save_settins AJAX action. This makes it possible for unauthenticated attackers to modify plugin filter settings, update arbitrary options, or create new filter posts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
