Summary
Calico Inserts Sensitive Information into Log File
Details

In Calico, the install-cni init container logs the rendered CNI configuration to standard output. When the configuration template uses the SERVICEACCOUNT_TOKEN placeholder (Canal/Flannel-Calico deployments), the installer substitutes the live Kubernetes ServiceAccount bearer token before logging, exposing the token to any authenticated user with pods/log permission in the namespace with calico-node. The token holds patch privileges on pods/status, enabling annotation-based attacks against cluster workloads. The default kubeconfig-based authentication path is not affected. This is a direct regression of TTA-2018-001.
