CVE-2026-53638 (opens in a new tab)How to fix?
Upgrade sylius/sylius to version 2.0.18, 2.1.15, 2.2.6 or higher.
Overview
sylius/sylius is a platform for PHP, based on Symfony framework.
Affected versions of this package are vulnerable to Incorrect Authorization in the PATCH /api/v2/shop/account/orders/{tokenValue}/payments/{paymentId} endpoint. An attacker can assign payment methods that are not enabled for the order's channel by sending crafted API requests as an authenticated user. This allows bypassing channel-based payment restrictions set by the store operator.
Workaround
This vulnerability can be mitigated by decorating the Sylius\Bundle\ApiBundle\Changer\PaymentMethodChangerInterface service in the application to enforce channel checks before changing payment methods.
