Overview
Affected versions of this package are vulnerable to Missing Authorization via the GetOverview handler in pkg/system/handler.go. An attacker can retrieve aggregate inventory and capacity data for a cluster they are not allowed to access by sending GET /api/v1/overview with x-cluster-name set to that cluster while authenticated with any role. This exposes the target cluster’s node, pod, namespace, service, CPU, and memory totals to a low-privileged user, bypassing the cluster membership checks used by other Kite endpoints.
