Name of the Vulnerable Software and Affected Versions The Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag & Drop WP Form Builder plugin for WordPress versions up to, and including, 5.1.19

Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping. This allows authenticated attackers with Administrator-level access and above to inject arbitrary web scripts in pages, which will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 5.1.19, update to a version higher than 5.1.19 to resolve the issue. As a temporary workaround, consider restricting access to the plugin's functionality to minimize the risk of exploitation.
