Detailed vulnerability description
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to the way kubeclient parses kubeconfig files. When the kubeconfig file does not configure custom CA to verify certs,
kubeclient ends up accepting any certificate (it wrongly returns
VERIFY_NONE). A remote attacker can perform MitM attack.
