Summary

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.

Risk Assessment

An on-path attacker can capture Kubernetes cluster credentials and modify communication, leading to unauthorized access and cluster integrity breach. The risk includes full cluster compromise.

Recommendation

Upgrade maclof kubernetes-client to version 0.32.0 or later, which properly handles missing certificate-authority-data, and ensure kubeconfig files contain valid certificate data.
