github.com/kubernetes/kubernetes is vulnerable to Misconfiguration of LoadBalancer Service. The vulnerability is present in the proxier.go. In the context of Kube-proxy on Windows, there is an issue where it can inadvertently forward traffic to local processes that are listening on the same port as specified in the spec.ports[*].port of a LoadBalancer Service. This happens when the LoadBalancer controller fails to set the status.loadBalancer.ingress[].ip field. Clusters where the LoadBalancer controller correctly sets the status.loadBalancer.ingress[].ip fields are not affected by this vulnerability
