Description The plugin is vulnerable to Stored Cross-Site Scripting via form settings due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with access to the Fluent Forms settings, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This can be chained with CVE-2024-2771 for a low-privileged user to inject malicious web scripts.
