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.\n\n## Affected\n\n- `advanced_cluster_management_for_kubernetes = 2.0`\n- `insights-client`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:60387** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.11 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60387)\n- **RHSA-2026:60390** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.13 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60390)\n- **RHSA-2026:60388** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.14 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60388)\n- **RHSA-2026:60389** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.15 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60389)\n- **RHSA-2026:60391** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.16 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60391)\n- **RHSA-2026:60386** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.17 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60386)","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
