Summary

The Fluent Forms plugin for WordPress is affected in all versions through 6.2.5. It does not check authorization, so authenticated users with Custom-level access or above can read private form submissions, change submission statuses, permanently delete submissions, and modify global plugin settings (CWE-862). Exploitation has not been reported, and CISA has not added the flaw to the KEV catalog.

Description from the CNA

The Fluent Forms plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.2.5. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with Custom-level access and above, to read private form submissions, change submission statuses, permanently delete submissions, and modify global plugin settings.
