Official description
The Integration for Freshsales – Contact Form 7, WPForms, Elementor, Gravity Forms and More plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Form Submission Data in all versions up to, and including, 1.0.15 due to insufficient input sanitization and output escaping.
