CVE-2026-71846
Full vulnerability record from the local CVENow database.
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.

La ServiceAccount del componente está vinculada a un ClusterRole que otorga permisos de get, list y watch sobre secretos a nivel de clúster, mientras que el código solo requiere acceso a un único Secret específico. Este privilegio excesivo significa que un compromiso del pod de insights-cliente o del token de ServiceAccount otorgaría a un atacante acceso de lectura a todos los Secrets en todo el clúster central, incluyendo los kubeconfigs de los clústeres gestionados y otras credenciales sensibles."
