CNTR-K8-000220 - The Kubernetes Controller Manager must create unique service accounts for each work payload.


The Kubernetes Controller Manager is a background process that embeds core control loops regulating cluster system state through the API Server. Every process executed in a pod has an associated service account. By default, service accounts use the same credentials for authentication. Implementing the default settings poses a High risk to the Kubernetes Controller Manager. Setting the '--use-service-account-credential' value lowers the attack surface by generating unique service accounts settings for each controller instance.


Edit the Kubernetes Controller Manager manifest file in the /etc/kubernetes/manifests directory on the Kubernetes Control Plane.

Set the value of '--use-service-account-credentials' to 'true'.
