Name of the Vulnerable Software and Affected Versions Fluent Forms – Customizable Contact Forms, Survey, Quiz, & Conversational Form Builder versions prior to 6.2.1

Description An Insecure Direct Object Reference (IDOR) exists in the exportEntries() function due to missing validation on a user-controlled key. This allows authenticated attackers with manager-level access or higher to bypass form-level restrictions to access unauthorized form submissions, export data from arbitrary database tables, and enumerate database table names through error message disclosure.

Recommendations Update to a version later than 6.2.0. As a temporary workaround, restrict access to the exportEntries() function for users with manager-level permissions until the update is applied.
