Doc Text:	A Kubernetes tenant with create permission on Console custom resources can set spec.containers.api.spec.image to an arbitrary container image. The operator deploys this image into a pod whose ServiceAccount is bound via ClusterRoleBinding to a ClusterRole granting cluster-wide get/list/watch on all Strimzi CRDs (including KafkaUsers), patch on Kafkas/KafkaRebalances, and cluster-monitoring-view. The attacker's code reads the projected SA token and gains cross-tenant Strimzi control-plane read+write access.	Story Points:	---

Description OSIDB Bzimport 2026-08-04 01:33:56 UTC

Source: Internal security audit — Streams for Apache Kafka Console f001
Upstream project: StreamsHub Console (Red Hat-owned, github.com/streamshub/console)
Upstream advisory: N/A — Red Hat-owned code, no external disclosure needed

Affected code:
- ConsoleDeployment.java — passes tenant-supplied spec.containers.api.spec.image verbatim to .withImage() with zero validation
- ClusterRoleBinding grants console-server SA cluster-wide Strimzi CRD access

Fix status: Unfixed in upstream main and all downstream versions. Requires image allowlist validation or removal of tenant image override capability.
