CVE-2026-19274 updated by NVD
Summary
IBM Observability with Instana (Agent) Build 1.0.303 through 1.0.323 IBM Instana Agent Operator could allow an authenticated Kubernetes tenant to hijack or permanently destroy another tenant's cluster-level RBAC permissions, caused by cluster-scoped RBAC objects being keyed solely by the bare CR name with no namespace disambiguation, allowing a same-named `InstanaAgent` CR in an attacker-controlled namespace to silently overwrite the shared `ClusterRoleBinding` or delete it outright and revoke the victim agent's cluster monitoring access.
