CVE-2026-31825

描述

### Impact Sylius API filters `ProductPriceOrderFilter` and `TranslationOrderNameAndLocaleFilter` pass user-supplied order direction values directly to Doctrine's `orderBy()` without validation. An attacker can inject arbitrary DQL: ``` GET /api/v2/shop/products?order[price]=ASC,%20variant.code%20DESC ``` ### Patches The issue is fixed in versions: 1.9.12, 1.10.16, 1.11.17, 1.12.23, 1.13.15, 1.14.18, 2.0.16, 2.1.12, 2.2.3 and above. ### Workarounds An `EventSubscriber` that sanitizes `order` query parameters **only on API routes** before they reach the vulnerable filters. The subscriber accepts an `$apiRoute` constructor parameter (default `/api/v2`) and skips non-API requests entirely — so there is zero overhead on shop/admin page requests. This follows the same pattern used by Sylius's own `KernelRequestEventSubscriber` (`src/Sylius/Bundle/ApiBundle/EventSubscriber/KernelRequestEventSubscriber.php`), which also uses `str_contains($pathInfo, $this->apiRoute)` to scope logic to API routes. --- #### Step 1 — Create the EventSubscriber `src/EventSubscriber/SanitizeOrderDirectionSubscriber.php`: ```php <?php declare(strict_types=1); namespace App\EventSubscriber; use Symfony\Component\EventDispatcher\EventSubscriberInterface; use Symfony\Component\HttpKernel\Event\RequestEvent; use Symfony\Component\HttpKernel\KernelEvents; final class SanitizeOrderDirectionSubscriber implements EventSubscriberInterface { private const ALLOWED_DIRECTIONS = ['asc', 'desc']; public function __construct( private string $apiRoute, ) { } public static function getSubscribedEvents(): array { return [ KernelEvents::REQUEST => ['sanitizeOrderParameters', 64], ]; } public function sanitizeOrderParameters(RequestEvent $event): void { if (!str_contains($event->getRequest()->getPathInfo(), $this->apiRoute)) { return; } $request = $event->getRequest(); /** @var mixed $order */ $order = $request->query->all()['order'] ?? null; if (!is_array($order)) { return; } $needsSanitization = false; $sanitized = []; foreach ($order as $field => $direction) { if (is_string($direction) && in_array(strtolower($direction), self::ALLOWED_DIRECTIONS, true)) { $sanitized[$field] = $direction; } else { $needsSanitization = true; } } if (!$needsSanitization) { return; } $all = $request->query->all(); $all['order'] = $sanitized; $request->query->replace($all); $request->server->set('QUERY_STRING', http_build_query($all)); $request->attributes->set('_api_filters', $all); } } ``` #### Step 2 — Register the service **Option A** — If your `config/services.yaml` already has `App\` autowiring (Symfony default): ```yaml # Nothing to do — autoconfigure picks up EventSubscriberInterface automatically. # Optionally bind the API route prefix: services: App\EventSubscriber\SanitizeOrderDirectionSubscriber: arguments: $apiRoute: '%sylius.security.new_api_route%' ``` **Option B** — If there is no `App\` autowiring: ```yaml services: App\EventSubscriber\SanitizeOrderDirectionSubscriber: arguments: $apiRoute: '%sylius.security.new_api_route%' tags: ['kernel.event_subscriber'] ``` Using `%sylius.security.new_api_route%` ties the subscriber to the same prefix Sylius uses (`/api/v2` by default). If the parameter is not available, hardcode `'/api/v2'` instead. #### Step 3 — Clear 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: - Chris Alupului (@Neosprings) - Bartłomiej Nowiński (@bnBart) ### 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 [[email protected]](mailto:[email protected])
