Forminator Forms < 1.55.1 - Unauthenticated Draft Form Entry Disclosure via 'draft' Parameter

Description

The plugin is vulnerable to Insecure Direct Object Reference via the 'draft' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to enumerate sequential integer entry IDs via the 'draft' parameter and read other users' saved draft form data, including names, email addresses, phone numbers, addresses, and free-form message content. This is only exploitable on forms that have the 'Save and Continue' feature enabled.
