CVE-2025-66623: Linuxfoundation Strimzi

High severity, CVSS 7.4. EPSS: 0.2% 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. From 0.47.0 and prior to 0.49.1, in some situations, Strimzi creates an incorrect Kubernetes Role which grants the Apache Kafka Connect and Apache Kafka MirrorMaker 2 operands the GET access to all Kubernetes Secrets that exist in the given Kubernetes namespace. The issue is fixed in Strimzi 0.49.1.

Affected products

• Linuxfoundation Strimzi: before 0.49.1 (fixed in 0.49.1)
