Detailsinfo

A vulnerability was found in Red Hat StreamsHub Console (version now known) and classified as problematic. This issue affects some unknown processing of the component Operator. The manipulation of the argument namespace with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality. The summary by CVE is:

The StreamsHub Console operator acts as a confused deputy: a Kubernetes tenant with permission to create a Console custom resource can set spec.kafkaClusters[].credentials.kafkaUser.namespace to any namespace. The operator, running with cluster-wide Secrets RBAC, reads the victim-namespace KafkaUser Secret (SASL credentials or TLS private keys) and writes the plaintext material into a Secret in the attacker's namespace. No same-namespace check or allowlist exists anywhere in the code path.
