Vulnerability Overview

The Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag & Drop WP Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘description’ and 'btn_txt' parameters in all versions up to, and including, 5.1.19 due to insufficient input sanitization and output escaping.
