## Description

The FunnelKit Payment Gateway for Stripe WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference via the order-pay page in version 1.15.0.1, due to the plugin loading the order named in the 'order-pay' endpoint without checking the order key or that the order belongs to the current user, then printing that order's billing details and Google Pay line items into the page's script data. This makes it possible for unauthenticated attackers to step through sequential order IDs and read other customers' billing name, email address, phone number and postal address, and the items they ordered.
