Description
The Fluent Forms plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in versions 6.2.0 up to, and including, 6.2.13. This is due to the submissions bulk-action and print endpoints authorizing the request against the form of a request-supplied entry_id while acting on a separately supplied form_id. This makes it possible for authenticated attackers who have been granted Fluent Forms entry-management access restricted to specific forms to change the status of, permanently delete, or print entries belonging to any other form. This requires a non-default configuration in which an administrator has created a manager restricted to specific forms.
