CVE-2026-53638

描述

### Impact An authorization bypass vulnerability exists in the shop account API. The `PATCH /api/v2/shop/account/orders/{tokenValue}/payments/{paymentId}` endpoint, used by an authenticated shop customer to change the payment method of an order that has been placed but not yet paid (state `STATE_NEW`), does not validate that the chosen payment method is enabled for the order's channel. The equivalent checkout endpoint (`PATCH /api/v2/shop/orders/{tokenValue}/payments/{paymentId}`) correctly rejects out-of-channel payment methods with `HTTP 422`; the account endpoint silently accepts them and returns `HTTP 200`. An authenticated customer can therefore assign any globally enabled payment method to their own placed order, including methods that the store operator has explicitly excluded from that channel. ### Patches The issue is fixed in versions: 2.0.18, 2.1.15, 2.2.6 and above. ### Workarounds If users cannot bump Sylius right now, decorate the `Sylius\Bundle\ApiBundle\Changer\PaymentMethodChangerInterface` service in their applications. #### Step 1. Create the decorator `src/Decorator/ChannelCheckingPaymentMethodChanger.php`: ```php <?php declare(strict_types=1); namespace App\Decorator; use ApiPlatform\Validator\Exception\ValidationException; use Sylius\Bundle\ApiBundle\Changer\PaymentMethodChangerInterface; use Sylius\Component\Core\Model\OrderInterface; use Sylius\Component\Core\Model\PaymentMethodInterface; use Sylius\Component\Core\Repository\PaymentMethodRepositoryInterface; use Sylius\Component\Core\Repository\PaymentRepositoryInterface; use Sylius\Component\Payment\Resolver\PaymentMethodsResolverInterface; use Symfony\Component\Validator\ConstraintViolation; use Symfony\Component\Validator\ConstraintViolationList; use Symfony\Contracts\Translation\TranslatorInterface; final readonly class ChannelCheckingPaymentMethodChanger implements PaymentMethodChangerInterface { public function __construct( private PaymentMethodChangerInterface $decorated, private PaymentRepositoryInterface $paymentRepository, private PaymentMethodRepositoryInterface $paymentMethodRepository, private PaymentMethodsResolverInterface $paymentMethodsResolver, private TranslatorInterface $translator, ) { } public function changePaymentMethod(string $paymentMethodCode, mixed $paymentId, OrderInterface $order): OrderInterface { /** @var PaymentMethodInterface|null $paymentMethod */ $paymentMethod = $this->paymentMethodRepository->findOneBy(['code' => $paymentMethodCode]); $payment = $this->paymentRepository->findOneByOrderId($paymentId, $order->getId()); if ( $paymentMethod !== null && $payment !== null && !in_array($paymentMethod, $this->paymentMethodsResolver->getSupportedMethods($payment), true) ) { $template = 'sylius.payment_method.not_available'; $parameters = ['%name%' => (string) $paymentMethod->getName()]; throw new ValidationException(new ConstraintViolationList([ new ConstraintViolation( message: $this->translator->trans($template, $parameters, 'validators'), messageTemplate: $template, parameters: $parameters, root: $paymentMethodCode, propertyPath: '', invalidValue: $paymentMethodCode, ), ])); } return $this->decorated->changePaymentMethod($paymentMethodCode, $paymentId, $order); } } ``` #### Step 2. Register the decorator `config/services.yaml` (append to the application's existing `services:` block): ```yaml services: App\Decorator\ChannelCheckingPaymentMethodChanger: decorates: sylius_api.changer.payment_method arguments: - '@.inner' - '@sylius.repository.payment' - '@sylius.repository.payment_method' - '@sylius.resolver.payment_methods' - '@translator' ``` `@.inner` references the original `PaymentMethodChangerInterface` implementation, so any future Sylius change to the changer keeps working through the decorator. #### Step 3. Clear the cache ```bash bin/console cache:clear ``` ### Reporters We would like to extend our gratitude to the following individuals for their detailed reporting and responsible disclosure of this vulnerability: - Fredrik Dietrichson (@FredrikEV) ### For more information If there are any questions or comments about this advisory: - Open an issue in [Sylius issues](https://github.com/Sylius/Sylius/issues?q=sort%3Aupdated-desc+is%3Aissue+is%3Aopen) - Send an email to [security@sylius.com](mailto:security@sylius.com)
