CVE-2026-53487
Kite has an authenticated cluster RBAC bypass in /api/v1/overview
Impact
Kite is a Kubernetes dashboard. Prior to version 0.12.3, authenticated Kite users with any role can request `/api/v1/overview` for a cluster that their roles do not permit by selecting that cluster with `x-cluster-name`. The overview route is registered before `middleware.RBACMiddleware()` and `GetOverview` only checks `len(user.Roles) > 0`, so it returns aggregate Kubernetes inventory and capacity data from unauthorized clusters. Version 0.12.3 fixes the issue.
