Additionally, the openshift authentication strategy accepted tokens that could not view any namespace. An attacker with any valid OpenShift token could read other tenants' workload names, health, traffic topology, workload identities, pod addresses and mesh policies, resulting in information disclosure across tenant boundaries."], "mitigation": {"lang": "en:us", "value": "Set kiali_internal.health_cache.enabled to false to close the health endpoint exposure, and add logs-tab to kiali_feature_flags.disabled_features to close the ztunnel log exposure.

In Red Hat OpenShift Service Mesh, authenticated users or service accounts can retrieve cross-namespace metrics and operational logs beyond their assigned RBAC permissions. Because the flaw cannot be leveraged for remote code execution or privilege escalation to alter cluster resources, its overall risk remains limited.", "threat_severity": "Moderate"}
