CVE-2026-105223— maclof kubernetes-client 0.17.0 before 0.32.0 Disabled TLS Certificate Verification

Quick assessment

Affected
maclof kubernetes-client
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

maclof kubernetes-client 在 0.17.0 至 0.32.0（不含 0.32.0）版本中，当 kubeconfig 配置文件缺少 certificate-authority-data 字段时，parseKubeconfig() 和 parseKubeconfigFile() 方法会禁用 TLS 证书验证，同时忽略 insecure-skip-tls-verify 设置。这使得中间人攻击者能够伪装成 Kubernetes API 服务器，窃取 Bearer Token 或 Basic 认证凭据
