Name of the Vulnerable Software and Affected Versions Fluent Forms plugin for WordPress versions up to, and including, 6.0.2

Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping in the form-submission.js script. This allows 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.

Recommendations For versions up to, and including, 6.0.2, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the form-submission.js script to minimize the risk of exploitation.
