What is CVE-2026-71846?
CVE-2026-71846 is a medium-severity vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2.11, published on 12 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
A 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.
