What is CVE-2025-66623?

The Strimzi Kafka Operator, which enables the deployment of Apache Kafka clusters on Kubernetes or OpenShift, contains a vulnerability that can lead to improper access control. Specifically, in versions 0.47.0 through 0.48.0, a misconfigured Kubernetes Role may inadvertently allow Kafka Connect and MirrorMaker 2 components access to all Kubernetes Secrets within a namespace. This issue poses a significant risk as it could expose sensitive information stored in these Secrets. The vulnerability has been addressed in Strimzi version 0.49.1, where the correct Kubernetes Role permissions have been implemented.

Affected Version(s)

strimzi-kafka-operator >= 0.47.0, < 0.49.1
