What it is

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.
