Overview

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

The SureForms – Contact Form, Payment Form & Other Custom Form Builder plugin for WordPress is vulnerable to Payment Amount Bypass in all versions up to, and including, 2.5.2. This is due to the create_payment_intent() function performing a payment validation solely based on the value of a user-controlled parameter. This makes it possible for unauthenticated attackers to bypass configured form payment-amount validation and create underpriced payment/subscription intents by setting form_id to 0.
