CVE-2026-71846: Red Hat Advanced Cluster Management For Kubernetes

Medium severity, CVSS 6.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Red Hat Advanced Cluster Management For Kubernetes: version 2.0 only
• Red Hat Insights-Client: affected versions not specified
