CVE-2026-55225: Red Hat Streams For Apache Kafka 2

High severity, CVSS 8.0. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Red Hat Streams For Apache Kafka 2
• Red Hat Streams For Apache Kafka 3.2.1
• Strimzi Strimzi-Kafka-Operator: before 1.0.1 (fixed in 1.0.1)
