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, 1.14.0.1. This is due to missing validation of the order key and order ownership when the plugin builds the order-pay billing details and Google Pay cart data from the user-controlled 'order-pay' order ID. This makes it possible for unauthenticated attackers to enumerate order IDs and obtain other customers' billing names, email addresses, postal addresses, phone numbers, order line items and totals, which are embedded in the localized script data of the order-pay page.
