CVE-2026-5396

A security flaw exists in versions 6.1.21 and earlier of the Fluent Forms plugin for WordPress due to inadequate validation of user-submitted data. Specifically, the SubmissionPolicy class grants submission-level permissions based on a form ID provided by users through the query parameter. As a result, authorized attackers can manipulate this ID to access submissions from other forms they have permission to manage.
