CVE-2026-62246Public exploitNetwork attack vector

Cross-tenant compromise via lossy identifier normalization

Published Jul 30, 2026 · Updated Jul 30, 2026

Improper isolation in Clastix Kamaji before 26.7.4-edge allows remote authenticated users to compromise another tenant's Kubernetes state. Kamaji replaces hyphens with underscores after joining each TenantControlPlane namespace and name, causing distinct pairs to reuse one schema, login, or etcd prefix. Exploitation requires TenantControlPlane creation rights, a colliding identifier, and the same shared DataStore; it permits reading, modifying, or destroying victim state.
