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.

Kube-proxy may unintentionally forward traffic in k8s.io/kubernetes
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.
Kube-proxy en Windows puede reenviar tráfico involuntariamente a procesos locales que escuchan en el mismo puerto (“spec.ports[*].port”) que LoadBalancer Service cuando el controlador LoadBalancer no configura “status.loadBalancer.ingress[].ip”. Los clústeres donde el controlador LoadBalancer establece el campo "status.loadBalancer.ingress[].ip" no se ven afectados.
