Forminator Forms < 1.50.3 - Admin+ Stored XSS

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the form_name parameter 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.
