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)
