Unauthenticated SSRF and resource exhaustion via devfiles
Published Sep 18, 2026 · Updated Sep 18, 2026
SSRF and resource exhaustion in Red Hat OpenShift Container Platform 4 allow remote attackers to read internal responses or interrupt console service. The unauthenticated /api/devfile/ and /api/devfile/samples/ handlers accept crafted devfiles that direct the console pod to internal services, while repeated large requests without a Content-Length cause unbounded memory growth. No account is required; SSRF reflects partial internal responses, and sustained oversized traffic can exhaust console-pod memory and interrupt service.
