CVE-2026-62246: CWE-284: Improper Access Control in clastix kamaji
Kamaji, a Hosted Control Plane Manager for Kubernetes, has an improper access control vulnerability prior to version 26.7.4-edge. The issue arises from a lossy normalization process that causes distinct tenants with colliding normalized identifiers to share control-plane state. This allows unauthorized tenants to read, modify, or destroy another tenant's Kubernetes data. The vulnerability is fixed in version 26.7.4-edge.
AI Analysis
Technical Summary
CVE-2026-62246 describes an improper access control vulnerability (CWE-284) in clastix Kamaji before version 26.7.4-edge. Kamaji derives tenant-specific datastore schema, database user, and etcd key prefix using a lossy normalization of namespace and name in the functions GetDefaultDatastoreSchema() and GetDefaultDatastoreUsername(). This normalization can cause collisions between distinct tenants, resulting in shared control-plane state. Consequently, tenants with colliding normalized identifiers can access, modify, or destroy each other's Kubernetes data. The issue is resolved in Kamaji version 26.7.4-edge.
Potential Impact
The vulnerability allows unauthorized tenants to access and manipulate Kubernetes control-plane data belonging to other tenants. This can lead to data confidentiality breaches, integrity violations, and availability disruptions within the multi-tenant Kubernetes environment managed by Kamaji.
Mitigation Recommendations
A fix is available in Kamaji version 26.7.4-edge. Users should upgrade to this version or later to remediate the vulnerability. No other mitigation guidance is provided.
