Description
maclof kubernetes-client 0.17.0 before 0.32.0 disables TLS certificate verification in parseKubeconfig() and parseKubeconfigFile() when a kubeconfig lacks certificate-authority-data, ignoring insecure-skip-tls-verify. On-path attackers can impersonate the Kubernetes API server to capture Bearer tokens or Basic credentials and tamper with WebSocket or REST API traffic.
