The Formidable Forms – Contact Form, Survey, Quiz, Payment, Calculator Form & Custom Form Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.7.2. This is due to missing or incorrect nonce validation on the updatesettings function. This makes it possible for unauthenticated attackers to change form settings and add malicious JavaScript via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
