How to fix?
kubeclient to version 4.9.3 or higher.
kubeclient is a client for Kubernetes REST API.
Affected versions of this package are vulnerable to Improper Certificate Validation via the parsing process of
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), which can lead to a man-in-the-middle attack.
