| Description | 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. |

Workarounds
CNA: 1. Restrict Console CR RBAC — remove create/update/patch verbs on consoles.console.streamshub.github.com from tenant-level Roles. Only cluster administrators should manage Console CRs. 2. Deploy admission webhook — use OPA/Gatekeeper or Kyverno policy to validate spec.containers.api.spec.image against a trusted registry allowlist. 3. Apply network policies — restrict console-api pod egress to only required endpoints. 4. Single-tenant deployment — deploy the Console operator where only trusted administrators manage Console CRs.
