Shopware is an open commerce platform. Prior to 6.6.10.18 and 6.7.10.1, the /api/_action/media/external-link endpoint allows authenticated admin users to make server-side HTTP HEAD requests to arbitrary internal IP addresses. While the parallel uploadFromURL flow validates target IPs against private/reserved ranges via FileUrlValidator, the linkURL flow only performs a URL format check (regex for http:// or https:// prefix), allowing SSRF to internal network services and cloud metadata endpoints. This issue is fixed in versions 6.6.10.18 and 6.7.10.1.
