Description
The FunnelKit Payment Gateway for Stripe WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference via the order-pay page's localized script data in all versions up to, and including, 1.14.0.3, due to missing validation of the order key and order ownership when loading the order referenced by the 'order-pay' query variable. The plugin printed that order's billing details (name, email, phone, address) into the page's JavaScript data, and the Google Pay gateway added its line items and totals. This makes it possible for unauthenticated attackers to enumerate sequential order IDs and obtain other customers' personal information and order details.
