Description
The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the form_name parameter in all versions up to, and including, 1.50.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The plugin allows admins to give form management permissions to lower level users, which could make this exploitable by users such as subscribers.
Problem types
CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
