How to fix?

Upgrade sylius/mollie-plugin to version 2.2.8, 3.2.4, 3.3.1 or higher.

Overview

Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key via the sylius_mollie_shop_payment_webhook process. An attacker can manipulate the payment status of any order by submitting a valid Mollie payment ID together with a victim's order ID, causing the order's payment state to be updated without actual funds being transferred. This is possible because the process does not verify that the Mollie payment ID belongs to the referenced order, and the endpoint lacks authentication, CSRF protection, and rate limiting, allowing unauthenticated attackers to exploit the issue at scale.

Workaround

This vulnerability can be mitigated by decorating the plugin's webhook controller to ensure the incoming Mollie payment ID matches the ID stored for the order before processing the request.
