Streamshub/console: console-operator: streams for apache kafka console: unfiltered kafka client properties → sa-token exfiltration via config.providers

Published Sep 28, 2026 · Updated Nov 3, 2026 · Assigned by redhat

Description

A flaw was found in the StreamsHub Console for Apache Kafka. Tenant-supplied Kafka client properties from the Console custom resource are copied into the console-api AdminClient configuration without filtering security-sensitive keys, allowing a Console CR author to set config.providers and bootstrap.servers to exfiltrate the console-api ServiceAccount token to an attacker-controlled broker.
