CVE-2026-62246 PUBLISHED

Kamaji: TenantControlPlane namespace/name collision binds two tenants to the same SQL datastore schema + DB user, breaking per-tenant isolation

Assigner: GitHub_M
Reserved: 13.07.2026 Published: 30.07.2026 Updated: 30.07.2026

Kamaji is the Hosted Control Plane Manager for Kubernetes. Prior to 26.7.4-edge, Kamaji derives a TenantControlPlane datastore schema, database user, and etcd key prefix from a lossy namespace-and-name normalization in GetDefaultDatastoreSchema() and GetDefaultDatastoreUsername(), allowing distinct tenants with colliding normalized identifiers to share control-plane state and read, modify, or destroy another tenant's Kubernetes data. This issue is fixed in version 26.7.4-edge.
