Name of the Vulnerable Software and Affected Versions Kube-proxy versions (affected versions not specified)

Description The issue concerns Kube-proxy on Windows, which can unintentionally forward traffic to local processes listening on the same port (spec.ports[*].port) as a LoadBalancer Service. This occurs when the LoadBalancer controller does not set the status.loadBalancer.ingress[].ip field. Clusters where the LoadBalancer controller sets this field are unaffected.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
