The Kubernetes kube-controller-manager in versions v1.0-1.14, versions
prior to v1.15.12, v1.16.9, v1.17.5, and version v1.18.0 are vulnerable to
a Server Side Request Forgery (SSRF) that allows certain authorized users
to leak up to 500 bytes of arbitrary information from unprotected endpoints
within the master’s host network (such as link-local or loopback services).
