EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 4.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 93% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
