## Description

The FunnelKit Payment Gateway for Stripe WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference via the order-pay page in all versions up to, and including, 1.14.0.2, due to the plugin loading the order from the ID in the order-pay URL without checking the order key or the order's owner when it builds the billing details and Google Pay data it adds to the page's JavaScript. This makes it possible for unauthenticated attackers to enumerate order IDs and obtain other customers' billing information (name, email, phone and address) as well as order line items and totals.
