CVE-2026-71846
MediumCVSS 6.5Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
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.
Risk Assessment
Compromise of the pod or token could lead to full disclosure of secrets in the cluster, potentially resulting in takeover of managed clusters and compromise of the entire environment.
Recommendation
Update insights-client to a patched version. Restrict the ServiceAccount permissions to the minimum required, following the principle of least privilege.
