CVE-2021-25736: Kube-proxy may unintentionally forward traffic
(updated )
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.
