Description
The MONEI Payments for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference via the checkout payment-token parameter in all versions up to, and including, 7.3.7, due to the plugin loading the saved WooCommerce payment token named by a user-supplied ID and sending its MONEI token with the payment without checking that the token belongs to the current user. This makes it possible for unauthenticated attackers (through guest checkout, which WooCommerce allows by default) and authenticated customers to submit another customer's saved token ID and pay for their own orders with that customer's stored card.
