CVE-2026-48013 shopware vulnerability
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.

Fixed versions
- Apply the latest vendor-supported patched version.
How to fix it
CVE-2026-48013 affects shopware and involves server-side request forgery. Successful exploitation may make the server contact internal services or expose data that should not be reachable externally. Prioritize deployments that process untrusted input, expose the affected feature, or hold sensitive data. Upgrade shopware to 6.6.10.18, 6.7.10.1 or a later vendor-supported fixed release.
- Inventory every deployment, device, package, plugin, container, build, and environment that uses shopware.
- Compare the installed version with the recorded affected range: < 6.6.10.18, >= 6.7.0.0, < 6.7.10.1.
- Upgrade shopware to 6.6.10.18, 6.7.10.1 or a later vendor-supported fixed release.
- Until patched, restrict URL inputs and block outbound access to private, loopback, link-local, and cloud-metadata addresses.
- Review configuration, roles, tokens, network paths, and exposed endpoints connected to shopware; remove access that is not required.
- Review proxy, DNS, firewall, cloud-metadata, and application logs for requests to internal, loopback, link-local, or unusual external addresses.
- If exploitation is suspected, isolate affected assets, preserve evidence, rotate exposed credentials or keys, restore trusted data, and rebuild compromised systems before returning them to service.

Verify the fix
- Confirm every affected asset now runs the fixed vendor-supported release or has the documented mitigation for CVE-2026-48013 in place.
- Use a safe regression test to confirm the affected server-side request forgery path no longer produces the vulnerable behavior.
- Confirm temporary access controls, endpoint restrictions, network blocks, and least-privilege settings remain effective after the update.
- Review post-remediation logs and rerun Fixnx plus the relevant package, dependency, firmware, browser, or product-specific security check.
- Document affected assets, versions, changes, validation evidence, reviewed logs, and any credential rotation, cleanup, or replacement completed.
