CVE-2026-15178: Fluent Forms <= 6.2.5 - Missing Authorization to Authenticated (Custom+) Sensitive Data Exposure and Modification

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.
