OpenShift provides a set of default cluster roles that you can bind to users and groups cluster-wide or locally (per project namespace). Be mindful of the difference between local and cluster bindings. For example, if you bind the cluster-admin role to a user by using a local role binding, it might appear that this user has the privileges of a cluster administrator. This is not the case. Binding the cluster-admin to a user in a project grants super administrator privileges for only that project to the user.
조치 방법
조치 방식: 가이드 또는 인프라 패치
Identify all clusterrolebindings to the cluster-admin role. Check if they are used and if they need this role or if they could use a role with fewer privileges. Where possible, first bind users to a lower privileged role and then remove the clusterrolebinding to the cluster-admin role : oc delete clusterrolebinding [name]
