CVE-2026-120656 Details
Description
OpenKruise kruise-manager exposes an unauthenticated pprof endpoint, enabled by default, opening it on 0.0.0.0:8090, which can enable a DoS attack triggerable by any pod on the cluster network.
A denial-of-service vulnerability has been identified in OpenKruise kruise-manager versions through v1.9.1. The issue arises from an unauthenticated pprof endpoint that is enabled by default and exposed on all interfaces. This endpoint can be accessed by any pod with RBAC permissions, allowing for resource exhaustion attacks that disrupt the OpenKruise admission webhooks and block pod creation across the cluster.
Users can upgrade to OpenKruise version v1.9.2 or later, where this vulnerability has been addressed. If an immediate upgrade is not possible, pprof can be disabled by adding '--enable-pprof=false' to the kruise-manager container arguments. Alternatively, ingress to the kruise-manager pods on port 8090 can be restricted using a NetworkPolicy.
