Fluent Forms <= 6.1.7 - Unauthenticated Insecure Direct Object Reference to Payment Status Tampering via submission_id

Slug:

fluentform

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, 6.1.7 via the 'submission_id' parameter due to missing validation on a user controlled key within the confirmScaPayment() function. This makes it possible for unauthenticated attackers to mark arbitrary submissions as failed via crafted requests to the endpoint granted they can guess or enumerate a valid submission identifier.

CWE:

Authorization Bypass Through User-Controlled Key

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
