CVE-2026-71846 is a medium-severity flaw (CVSS 6.5) affecting advanced cluster management for kubernetes, insights-client. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 sens
