Stored Cross-Site Scripting vulnerability in Formidable Forms plugin for WordPress
CVE-2023-6842

4.8MEDIUM

Summary

The Formidable Forms plugin for WordPress is susceptible to Stored Cross-Site Scripting (XSS). This vulnerability arises from inadequate input sanitization and output escaping of the name and description field labels, which can be exploited by authenticated users with administrator-level access to inject malicious scripts. While primarily affecting multi-site installations and those with unfiltered HTML disabled, this flaw can also be exploited by users with extended permissions for form management, enabling lower-level users to carry out attacks on injected pages when accessed by other users.

Affected Version(s)

Formidable Forms – Contact Form, Survey, Quiz, Payment, Calculator Form & Custom Form Builder * <= 6.7
