Users may have access to secure endpoints in the control plane network.
Kubernetes clusters are only affected if an untrusted user can modify Node
objects and send proxy requests to them. Kubernetes supports node proxying,
which allows clients of kube-apiserver to access endpoints of a Kubelet to
establish connections to Pods, retrieve container logs, and more. While
Kubernetes already validates the proxying address for Nodes, a bug in
kube-apiserver made it possible to bypass this validation. Bypassing this
validation could allow authenticated requests destined for Nodes to to the
API server’s private network.
