Kube-proxy may unintentionally forward traffic
Quick fix
GHSA-35c7-w35f-xwgh — k8s.io/kubernetes: upgrade to the fixed version with the command below.
go get k8s.io/kubernetes@v1.21.0Details
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.
