CVE-2026-105312: Improper Privilege Management in Red Hat StreamsHub Console for Apache Kafka®
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.

Technical Analysis
This vulnerability arises because a Kubernetes tenant with create permission on Console custom resources can specify an arbitrary container image in spec.containers.api.spec.image. The operator deploys this image into a pod whose ServiceAccount is bound via ClusterRoleBinding to a ClusterRole with cluster-wide permissions including get/list/watch on all Strimzi CRDs, patch on Kafkas/KafkaRebalances, and cluster-monitoring-view. The attacker’s code can read the projected ServiceAccount token and leverage these permissions to gain cross-tenant control-plane read and write access, effectively compromising the multi-tenant environment.
Potential Impact
Successful exploitation grants an attacker cluster-wide read and write access to Strimzi custom resources across tenants, allowing unauthorized access and modification of Kafka users and cluster configurations. This compromises confidentiality, integrity, and availability of the Kafka control plane in a multi-tenant Kubernetes environment.
Mitigation Recommendations
Check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-105312 for official remediation guidance. Patch status is not yet confirmed from the provided data; therefore, verify the vendor advisory for current remediation steps. Until patched, restrict create permissions on Console custom resources to trusted users only to mitigate risk.
