CVE-2026-48015 shopware CVE debrief

Who should care

Users of Shopware versions prior to 6.6.10.18 and 6.7.10.1 should be aware of this vulnerability and take immediate action to update their installations. This vulnerability could potentially allow attackers to execute malicious JavaScript in the context of the Shopware domain. Affected operators, platforms, vulnerability-management, and security teams should review and act on this vulnerability.

Technical summary

The vulnerability exists due to the inclusion of SVG files in the allowed_extensions whitelist in src/Core/Framework/Resources/config/packages/shopware.yaml. This allows users to upload SVG files via the media manager without proper sanitization. The lack of sanitization enables malicious SVG files to execute JavaScript code, such as onload events, <script> tags, and <foreignObject> elements, when viewed within the Shopware domain. Users of Shopware versions prior to 6.6.10.18 and 6.7.10.1 should be aware of this vulnerability and take immediate action to update their installations.

Defensive priority

Medium priority due to the potential for JavaScript execution in the Shopware domain.

Recommended defensive actions

• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
