The POST and PUT handlers in endpoints/api/mirror.py accept an\nexternal_reference parameter without SSRF validation, unlike the\norganization-level mirror handlers which apply validate_external_registry_url().\nA repository administrator can supply a crafted hostname that causes the Quay\nmirror worker to make requests via Skopeo to internal network services, cloud\nmetadata endpoints, or other resources not intended to be reachable from the\nQuay application.",
