Kubernetes API server in all versions allow an attacker who is able to
create a ClusterIP service and set the spec.externalIPs field, to intercept
traffic to that IP address. Additionally, an attacker who is able to patch
the status (which is considered a privileged operation and should not
typically be granted to users) of a LoadBalancer service can set the
status.loadBalancer.ingress.ip to similar effect.
