Shopware is an open commerce platform. Prior to 6.6.10.18 and 6.7.10.1, the order state transition features /api/_action/order/{orderId}/state/{transition} and similar transaction and delivery transition routes in src/Core/Checkout/Order/Api/OrderActionController.php do not declare PlatformRequest::ATTRIBUTE_ACL or perform an explicit privilege check, so AclAnnotationValidator exits when route ACL metadata is absent and low-privileged users without order:update, order_transaction:update, or order_delivery:update can trigger StateMachineRegistry::transition() writes in SYSTEM_SCOPE. This issue is fixed in versions 6.6.10.18 and 6.7.10.1.

## Summary This is a vertical authorization bypass in the Admin API affecting order state transition features (`/api/_action/order/{orderId}/state/{transition}` and similar transaction/delivery transition routes). The root cause is that the transition action routes do not declare required server-side ACL privileges, allowing low-privileged users to pass the authorization boundary. As a result, authenticated users without `order:update` can still change order states, causing real security impact such as operational integrity loss, automation workflow misuse, and fulfillment/settlement/support process disruption.

## Description Shopware’s permission model requires server-side enforcement independent of UI guards. However, the dedicated order-state transition action endpoints are missing ACL metadata, so accounts without regular order update privileges can still submit transition requests that are processed by the backend. In real reproduction, the same low-privileged account receives 403 on the normal order update API, while the transition action API succeeds with 200 and updates order state in the database. The key point is that reproduction is possible through direct API calls regardless of UI access restrictions or hidden buttons. This is not a functional edge case; it is an implementation gap in authorization boundaries that enables privilege escalation behavior where a “read/limited-edit” user can control order lifecycle states.
