Shopware is an open commerce platform. Prior to 6.6.10.18 and 6.7.10.1, the Store API endpoint /store-api/handle-payment in src/Core/Checkout/Payment/SalesChannel/HandlePaymentMethodRoute.php accepts a user-controlled orderId and forwards it to src/Core/Checkout/Payment/PaymentProcessor.php without verifying order ownership or guest-order authentication, allowing a normal customer or guest context to trigger the payment flow for another user's order while /store-api/order enforces the expected ownership model. This issue is fixed in versions 6.6.10.18 and 6.7.10.1.
