CVE-2026-48016 shopware CVE debrief

Who should care

Users of Shopware versions prior to 6.6.10.18 and 6.7.10.1 should update to the latest versions to prevent potential unauthorized payment processing. This involves reviewing current deployments, identifying affected systems, and assigning owners for follow-up. Additionally, operators, platform administrators, vulnerability management teams, and security teams should be aware of the potential impact and take necessary precautions.

Technical summary

The Store API endpoint /store-api/handle-payment in Shopware accepts a user-controlled orderId and forwards it to PaymentProcessor.php without verifying order ownership or guest-order authentication. This allows a normal customer or guest context to trigger the payment flow for another user's order. The issue is fixed in versions 6.6.10.18 and 6.7.10.1. The vulnerability has a CVSS score of 4.3 and a severity of MEDIUM. To mitigate, defenders should focus on validating affected scope, reviewing compensating controls, and implementing additional authentication and authorization checks for payment handling.
