The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.55.0.2 via the 'draft' parameter due to missing validation on a user controlled key.

This is only exploitable on forms that have the 'Save and Continue' feature enabled.
