CyberRota Analysis
AI-GeneratedA vulnerability exists in Red Hat Quay's repository-level mirror configuration, where the POST and PUT handlers in the API fail to validate the external_reference parameter against server-side request forgery (SSRF) attacks. This flaw allows a repository administrator to craft a malicious hostname, enabling the Quay mirror worker to access internal network services or cloud metadata endpoints that should remain inaccessible. Organizations using Red Hat Quay, particularly those with sensitive internal resources, should prioritize addressing this issue to mitigate potential unauthorized access risks.
Original NVD Description
A flaw was found in Red Hat Quay's repository-level mirror configuration feature. The POST and PUT handlers in endpoints/api/mirror.py accept an external_reference parameter without SSRF validation, unlike the organization-level mirror handlers which apply validate_external_registry_url(). A repository administrator can supply a crafted hostname that causes the Quay mirror worker to make requests via Skopeo to internal network services, cloud metadata endpoints, or other resources not intended to be reachable from the Quay application.
