High [CVE-2026-55225] Cross-namespace privilege escalation via Kafka.spec.entityOperator.watchedNamespace in Strimzi
CVE-2026-55225Source published Source updated
Strimzi provides a way to run an Apache Kafka cluster on Kubernetes or OpenShift in various deployment configurations. In Strimzi 1.0.0 and earlier, an attacker who can create a Kafka custom resource can set Kafka.spec.entityOperator watchedNamespace to a target namespace, causing the Cluster Operator to create a Role with full Secret CRUD permissions there and bind it to the Entity Operator ServiceAccount in the attacker's namespace. The attacker can mint a token for that ServiceAccount and read or write Secrets in any target namespace where the Cluster Operator has been granted permissions, regardless of STRIMZI_NAMESPACE. This issue is fixed in versions 1.0.1 and 1.1.0. When the Strimzi cluster operator is deployed with watchAnyNamespace=true (or a multi-namespace list), any namespace…

- Mitigation guidance
- For users who cannot upgrade immediately, deploy a Kubernetes admission policy agent (such as Kyverno or OPA Gatekeeper) to block or restrict the use of the `watchedNamespace` field in Kafka custom resources (`Kafka.spec.entityOperator.userOperator.watchedNamespace` and `Kafka.spec.entityOperator.topicOperator.watchedNamespace`). Additionally, audit existing Kafka custom resources for unexpected `watchedNamespace` configurations and review RoleBindings in sensitive namespaces.
