Title
Integration for Freshsales <= 1.0.15 - Unauthenticated Stored Cross-Site Scripting via Form Submission Data
Summary
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. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload only executes when a CRM API call fails for the submitted form and an administrator subsequently views the error log details modal in the WordPress admin panel.
