Versions 2.0.0 through 2.0.17, 2.1.0 through 2.1.14, and 2.2.0 through 2.2.5 contain an improper workflow enforcement vulnerability in the cart `FormComponent`. When an order is completed while its cart page remains open, the stale LiveComponent does not detect the order\u2019s changed state and continues to permit cart actions, allowing an authenticated customer to modify or permanently delete an already completed order. Versions 2.0.18, 2.1.15, and 2.2.6 contain a patch. As a workaround, deployments can copy the patched `FormComponent` into the application\u0027s `src/` directory and override the `sylius_shop.twig.component.cart.form` service definition to use that class."

  "details": "### Impact\nA user opens the cart page in the browser. In the background, the order gets completed, e.g. an admin changes the status, or the user finalizes payment in another tab. The browser still displays the old cart: the LiveComponent is unaware the underlying order state has changed.\n\nIf the user then:\n\n- **clears the cart** \u2192 `clearCart()` calls `manager-\u003eremove()` on the\n  completed order: the order is permanently **deleted** from the database;\n- **removes a product** \u2192 `removeItem()` mutates an item on the completed\n  order;\n- **changes quantity** \u2192 `saveCart()` overwrites data on the completed order.\n\nIn all cases, the customer\u0027s order data is irreversibly corrupted or lost, even though the order has already been placed and paid for. The same vector can be triggered deliberately by an authenticated customer (keep the cart page open, complete checkout in another tab, then modify the \"cart\" to add quantity beyond what was paid for).\n\n### Patches\nThe issue is fixed in versions: 2.0.18, 2.1.15, 2.2.6 and above.\n\n### Workarounds\nIf users cannot update Sylius immediately, they should create a patched copy of the affected class in their application\u0027s `src/` directory and override the Sylius service definition to use it.\n\n#### Step 1.

Override the Sylius service in `config/services.yaml`\n\nAppend to the application\u0027s `config/services.yaml` (or a dedicated file loaded by the kernel, e.g. `config/packages/sylius_security_cart.yaml`):\n\n```yaml\nservices:\n    sylius_shop.twig.component.cart.form:\n        class: App\\Twig\\Component\\Cart\\FormComponent\n        arguments:\n            - \u0027@sylius.repository.order\u0027\n            - \u0027@form.factory\u0027\n            - \u0027%sylius.model.order.class%\u0027\n            - \u0027Sylius\\Bundle\\ShopBundle\\Form\\Type\\CartType\u0027\n            - \u0027@doctrine.orm.entity_manager\u0027\n            - \u0027@event_dispatcher\u0027\n        calls:\n            - [setLiveResponder, [\u0027@ux.live_component.live_responder\u0027]]\n        tags:\n            - { name: sylius.live_component.shop, key: \u0027sylius_shop:cart:form\u0027 }\n```\n\nThis redeclares the existing Sylius service id `sylius_shop.twig.component.cart.form` so it instantiates the patched class from `App\\` while preserving every argument, call and tag from the original Sylius XML definition. The cart twig hook keeps resolving to the same Live Component key (`sylius_shop:cart:form`).\n\n#### Step 3. Clear the cache\n\n```bash\nbin/console cache:clear\n```\n\n### Reporters\n\nWe would like to extend our gratitude to the following individuals for their detailed reporting and responsible disclosure of this vulnerability:\n- K\u00e9vin Gonella (@kgonella)\n- Sam V.\n\n### For more information\n\nIf there are any questions or comments about this advisory:\n\n- Open an issue in [Sylius issues](https://github.com/Sylius/Sylius/issues?q=sort%3Aupdated-desc+is%3Aissue+is%3Aopen)\n- Send an email to [security@sylius.com](mailto:security@sylius.com)",
