CVE-2026-6396 Details
Description
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.
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the Fast & Fancy Filter – 3F WordPress plugin, affecting versions through 1.2.2. The vulnerability arises from a lack of nonce verification in the 'saveFields' function, which processes the 'fff_save_settins' AJAX action. This omission allows unauthenticated attackers to manipulate plugin filter settings, alter arbitrary options, or create new filter posts by sending a forged request, provided they can deceive a site administrator into clicking a link.
