DescriptionA flaw was found in insights-client. The component's ServiceAccount is bound to a ClusterRole granting cluster-wide secrets get, list, and watch permissions, while the code only requires access to a single specific Secret. This excessive privilege means that a compromise of the insights-client pod or ServiceAccount token would grant an attacker read access to all Secrets across the hub cluster, including managed-cluster kubeconfigs and other sensitive credentials.

Workarounds

CNA: Restrict the insights-client ClusterRole to the minimum required permissions. Replace the cluster-wide secrets get/list/watch with a namespaced Role granting get access only to the specific Secret openshift-config/pull-secret in the openshift-config namespace.
