Description
The FunnelKit Payment Gateway for Stripe WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference via the order-pay endpoint in all versions up to, and including, 1.14.0.4, due to the gateway loading the order from the order ID in the URL without validating the order key or that the current user owns the order. The order's billing details (name, email, phone and address) and Google Pay order data (currency, line items and total) are then printed into front-end script data. This makes it possible for unauthenticated attackers to step through sequential order IDs and harvest other customers' personal information and order details.
