Authenticated node-network access via unrestricted probe Host
Published Feb 25, 2026 · Updated Feb 25, 2026
SSRF in OpenKruise Kruise before 1.7.5 and 1.8.0 through 1.8.2 allows remote authenticated users to scan node-reachable ports. The PodProbeMarker admission webhook validates only the TCP port and passes an attacker-supplied Host to the host-networked kruise-daemon. PodProbeMarker creation permission is required; NodePodProbe status distinguishes reachable from refused ports and exposes node-network reachability.
