Internal resource access via arbitrary log-export callback
Published Apr 8, 2026 · Updated Apr 8, 2026
SSRF in Red Hat Quay and Mirror Registry for Red Hat OpenShift allows remote authenticated users to access internal network resources. The log export feature accepts an arbitrary callback URL and directs a backend process to issue an HTTP request to that unvalidated destination. Repository administrator access is required; reachable internal services can disclose sensitive information, while Red Hat bounds the Mirror Registry blast radius to the core product.
