Strimzi: Cross-namespace privilege escalation via `Kafka.spec.entityOperator`

Impact Having the Topic and User operators to watch different namespaces than the one where the Kafka cluster is deployed, is a fully documented feature. When the watchedNamespace field is used within the Topic or User operator as part of the Kafka.spec.entityOperator field, the Cluster Operator...

Unintended Proxy or Intermediary ('Confused Deputy')

Overview Affected versions of this package are vulnerable to Unintended Proxy or Intermediary 'Confused Deputy' via the Kafka.spec.entityOperator process. An attacker can gain unauthorized access to read and modify secrets in other namespaces by crafting a custom resource with the watchedNamespac...

CVE-2026-55225

When the Strimzi cluster operator is deployed with watchAnyNamespace=true or a multi-namespace list, any namespace editor can set Kafka.spec.entityOperator.userOperator.watchedNamespace or topicOperator.watchedNamespace to an arbitrary namespace. The cluster operator then creates a Role granting...
