Description
The FunnelKit Payment Gateway for Stripe WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference via the order-pay page script data in all versions up to, and including, 1.14.0, due to the plugin loading the order straight from the 'order-pay' query variable when preparing localized billing details and Google Pay order data, without validating the order key or confirming that the requester owns the order. This makes it possible for unauthenticated attackers to enumerate sequential order IDs and obtain other customers' billing information (name, email address, postal address, phone number) as well as order line items and totals.
