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.
IBM strongly recommends addressing these vulnerabilities now by updating IBM Observability with Instana to the latest release as described here:
