Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. In Sylius, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The `GET /api/v2/shop/payment-requests/{hash}` and `PUT /api/v2/shop/payment-requests/{hash}` endpoints look up the payment request solely by the hash from the URL. No ownership check is performed against the authenticated customer or the underlying order. An attacker who obtains a payment request hash can: - read the payment request and, through the `payment` IRI in the response, recover the underlying order's `tokenValue` (which itself grants access to the full order, items, addresses, customer email, totals); - update the payment request payload (e.g. `target_path`, `after_path`). These fields are used by the front-end controller to redirect the user after the payment, so an attacker can flip them to an attacker-controlled URL and intercept the buyer. The hash is a UUID, so it has to be obtained out-of-band (logs, shared links, referrer headers, a co-located client), but once it is known no other credential is required, neither authentication nor knowledge of the order token. The creation endpoint `POST /api/v2/shop/orders/{tokenValue}/payment-requests` shares the same flaw: it resolves the target order solely from the `tokenValue` in the URL without verifying that the caller owns the order. ### Patches The issue is fixed in versions: 2.0.18, 2.1.15, 2.2.6. ### Workarounds Until you can upgrade, apply the following workaround. It enforces ownership on the existing endpoints, so that: - an authenticated shop user may only access payment requests of their own orders; - an anonymous caller may only access payment requests of guest orders (the order's customer has no associated user account); - everyone else receives `404 Not Found`. #### Step 1. Add a query extension that filters the `GET` operation Create file `src/ApiPlatform/QueryExtension/PaymentRequestOwnershipExtension.php`: ```php <?php declare(strict_types=1); namespace App\ApiPlatform\QueryExtension; use ApiPlatform\Doctrine\Orm\Extension\QueryItemExtensionInterface; use ApiPlatform\Doctrine\Orm\Util\QueryNameGeneratorInterface; use ApiPlatform\Metadata\Operation; use Doctrine\ORM\QueryBuilder; use Sylius\Bundle\ApiBundle\Context\UserContextInterface; use Sylius\Bundle\ApiBundle\SectionResolver\ShopApiSection; use Sylius\Bundle\CoreBundle\SectionResolver\SectionProviderInterface; use Sylius\Component\Core\Model\ShopUserInterface; use Sylius\Component\Payment\Model\PaymentRequestInterface; final readonly class PaymentRequestOwnershipExtension implements QueryItemExtensionInterface { public function __construct( private SectionProviderInterface $sectionProvider, private UserContextInterface $userContext, ) { } public function applyToItem( QueryBuilder $queryBuilder, QueryNameGeneratorInterface $queryNameGenerator, string $resourceClass, array $identifiers, ?Operation $operation = null, array $context = [], ): void { if (!is_a($resourceClass, PaymentRequestInterface::class, true)) { return; } if (!$this->sectionProvider->getSection() instanceof ShopApiSection) { return; } $rootAlias = $queryBuilder->getRootAliases()[0]; $paymentJoin = $queryNameGenerator->generateJoinAlias('payment'); $orderJoin = $queryNameGenerator->generateJoinAlias('order'); $customerJoin = $queryNameGenerator->generateJoinAlias('customer'); $userJoin = $queryNameGenerator->generateJoinAlias('user'); $createdByGuestParameterName = $queryNameGenerator->generateParameterName('createdByGuest'); $queryBuilder ->innerJoin(sprintf('%s.payment', $rootAlias), $paymentJoin) ->innerJoin(sprintf('%s.order', $paymentJoin), $orderJoin) ->leftJoin(sprintf('%s.customer', $orderJoin), $customerJoin) ->leftJoin(sprintf('%s.user', $customerJoin), $userJoin) ; $user = $this->userContext->getUser(); if ($user instanceof ShopUserInterface) { $customerParam = $queryNameGenerator->generateParameterName('customer'); $queryBuilder ->andWhere($queryBuilder->expr()->eq(sprintf('%s.customer', $orderJoin), sprintf(':%s', $customerParam))) ->setParameter($customerParam, $user->getCustomer()) ; return; } $queryBuilder ->andWhere( $queryBuilder->expr()->orX( $queryBuilder->expr()->isNull($userJoin), $queryBuilder->expr()->isNull(sprintf('%s.customer', $orderJoin)), $queryBuilder->expr()->andX( $queryBuilder->expr()->isNotNull($userJoin), $queryBuilder->expr()->eq(sprintf('%s.createdByGuest', $orderJoin), sprintf(':%s', $createdByGuestParameterName)), ), ), ) ->setParameter($createdByGuestParameterName, true) ; } } ``` #### Step 2. Decorate the `PUT` state provider Create file `src/ApiPlatform/StateProvider/PaymentRequestOwnershipProvider.php`: ```php <?php declare(strict_types=1); namespace App\ApiPlatform\StateProvider; use ApiPlatform\Metadata\Operation; use ApiPlatform\State\ProviderInterface; use Sylius\Bundle\ApiBundle\Context\UserContextInterface; use Sylius\Component\Core\Model\CustomerInterface; use Sylius\Component\Core\Model\OrderInterface; use Sylius\Component\Core\Model\PaymentInterface; use Sylius\Component\Core\Model\ShopUserInterface; use Sylius\Component\Payment\Model\PaymentRequestInterface; /** @implements ProviderInterface<PaymentRequestInterface> */ final readonly class PaymentRequestOwnershipProvider implements ProviderInterface { /** @param ProviderInterface<PaymentRequestInterface> $inner */ public function __construct( private ProviderInterface $inner, private UserContextInterface $userContext, ) { } public function provide(Operation $operation, array $uriVariables = [], array $context = []): array|object|null { $paymentRequest = $this->inner->provide($operation, $uriVariables, $context); if (!$paymentRequest instanceof PaymentRequestInterface) { return $paymentRequest; } if (!$this->isAccessible($paymentRequest)) { return null; } return $paymentRequest; } private function isAccessible(PaymentRequestInterface $paymentRequest): bool { $payment = $paymentRequest->getPayment(); if (!$payment instanceof PaymentInterface) { return false; } $order = $payment->getOrder(); if (!$order instanceof OrderInterface) { return false; } $user = $this->userContext->getUser(); if ($user instanceof ShopUserInterface) { $customer = $user->getCustomer(); return $customer instanceof CustomerInterface && $order->getCustomer() === $customer; } $customer = $order->getCustomer(); return null === $customer || null === $customer->getUser() || $order->isCreatedByGuest(); } } ``` #### Step 3. Guard the `POST` creation endpoint with a command-bus middleware The `POST /api/v2/shop/orders/{tokenValue}/payment-requests` operation is a `messenger: input` operation: it dispatches a `Sylius\Bundle\ApiBundle\Command\Payment\AddPaymentRequest` command whose `orderTokenValue` comes straight from the URL, so no query extension or state provider runs. Add a middleware on the Sylius command bus that loads the order, applies the same ownership rule, and aborts with `404` before the handler runs. Create file `src/Messenger/Middleware/PaymentRequestOwnershipMiddleware.php`: ```php <?php declare(strict_types=1); namespace App\Messenger\Middleware; use Sylius\Bundle\ApiBundle\Command\Payment\AddPaymentRequest; use Sylius\Bundle\ApiBundle\Context\UserContextInterface; use Sylius\Component\Core\Model\CustomerInterface; use Sylius\Component\Core\Model\OrderInterface; use Sylius\Component\Core\Model\ShopUserInterface; use Sylius\Component\Core\Repository\OrderRepositoryInterface; use Symfony\Component\HttpKernel\Exception\NotFoundHttpException; use Symfony\Component\Messenger\Envelope; use Symfony\Component\Messenger\Middleware\MiddlewareInterface; use Symfony\Component\Messenger\Middleware\StackInterface; final readonly class PaymentRequestOwnershipMiddleware implements MiddlewareInterface { /** @param OrderRepositoryInterface<OrderInterface> $orderRepository */ public function __construct( private OrderRepositoryInterface $orderRepository, private UserContextInterface $userContext, ) { } public function handle(Envelope $envelope, StackInterface $stack): Envelope { $command = $envelope->getMessage(); if ($command instanceof AddPaymentRequest && !$this->isOrderAccessible($command->orderTokenValue)) { throw new NotFoundHttpException('Not Found'); } return $stack->next()->handle($envelope, $stack); } private function isOrderAccessible(string $orderTokenValue): bool { /** @var OrderInterface|null $order */ $order = $this->orderRepository->findOneByTokenValue($orderTokenValue); if (null === $order) { // Unknown token — let the handler return its own 404 (PaymentNotFoundException). return true; } $user = $this->userContext->getUser(); if ($user instanceof ShopUserInterface) { $customer = $user->getCustomer(); return $customer instanceof CustomerInterface && $order->getCustomer() === $customer; } $customer = $order->getCustomer(); return null === $customer || null === $customer->getUser() || $order->isCreatedByGuest(); } } ``` #### Step 4. Wire the services Append to `config/services.yaml`: ```yaml services: App\ApiPlatform\QueryExtension\PaymentRequestOwnershipExtension: arguments: - '@sylius.section_resolver.uri_based' - '@sylius_api.context.user.token_based' tags: - { name: api_platform.doctrine.orm.query_extension.item } App\ApiPlatform\StateProvider\PaymentRequestOwnershipProvider: decorates: sylius_api.state_provider.shop.payment.payment_request.item arguments: $inner: '@.inner' $userContext: '@sylius_api.context.user.token_based' App\Messenger\Middleware\PaymentRequestOwnershipMiddleware: arguments: - '@sylius.repository.order' - '@sylius_api.context.user.token_based' ``` With the default Sylius-Standard `services.yaml` (`autowire: true`, `autoconfigure: true`) the two classes are already autoloaded, the block above only adds the tag and the decoration, which cannot be derived from the constructor signatures. #### Step 5. Register the middleware on the Sylius command bus Add to `config/packages/messenger.yaml`: ```yaml framework: messenger: buses: sylius.command_bus: middleware: - 'App\Messenger\Middleware\PaymentRequestOwnershipMiddleware' - 'validation' - 'doctrine_transaction' ``` #### Step 6. 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: - Fase Rais Baradika (@baradika) - Anshu Chimala (@achimala) ### For more information If you have 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) - Email us at [security@sylius.com](mailto:security@sylius.com)
