Name of the Vulnerable Software and Affected Versions The Formidable Forms – Contact Form Plugin, Survey, Quiz, Payment, Calculator Form & Custom Form Builder plugin for WordPress versions up to, and including, 6.16.1.2

Description The issue is related to insufficient input sanitization and output escaping in the Custom HTML Form parameters, allowing unauthenticated attackers to inject arbitrary web scripts in pages. This can be achieved by tricking a user into performing an action, such as clicking on a link, which executes the injected script.

Recommendations For versions up to, and including, 6.16.1.2, update to a version later than 6.16.1.2 to resolve the issue. As a temporary workaround, consider restricting access to the Custom HTML Form parameters to minimize the risk of exploitation.
