## Affected

- techjewel Fluent Forms – Customizable Contact Forms, Survey, Quiz, & Conversational Form Builder: through 6.0.2

## Description

The Fluent Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the form-submission.js script in all versions up to, and including, 6.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
