Technical description

The Fluent Forms – Customizable Contact Forms, Survey, Quiz, & Conversational Form Builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.2.0 via the exportEntries function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Fluent Forms manager-level access and above, to bypass form-level access restrictions to access submissions from forms they are not authorized to view, export data from arbitrary database tables, and enumerate database table names via error message disclosure.
