DescriptionThe 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.
