Kube-proxy on Windows can unintentionally forward traffic to local processes listening on the same port (`spec.ports[*].port`) as a LoadBalancer Service when the LoadBalancer controller does not set the `status.loadBalancer.ingress[].ip` field. Clusters where the LoadBalancer controller sets the `status.loadBalancer.ingress[].ip` field are unaffected.
Update k8s.io/kubernetes to 1.21.0 if you use the affected versions. Test the change in a non-production environment first.

hol-guard supply-chain scanKube-proxy may unintentionally forward traffic affects k8s.io/kubernetes (go). Severity is medium. Kube-proxy on Windows can unintentionally forward traffic to local processes listening on the same port (`spec.ports[*].port`) as a LoadBalancer Service when the LoadBalancer controller does not set the `status.loadBalancer.ingress[].ip` field. Clusters where the LoadBalancer controller sets the `status.loadBalancer.ingress[].ip` field are unaffected.
AI coding agents often install or upgrade packages automatically in go. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.

|---|---|---|
| k8s.io/kubernetesgo | <1.21.0 | 1.21.0 |
Fixed versions are reported by the source feed; confirm compatibility before updating.
