CVE-2026-96740Streamshub/console: console-operator: streams for apache kafka console: unfiltered kafka client properties → sa-token exfiltration via config.providers
Medium 6.5
In plain English
A medium-severity security flaw in streams for Apache Kafka 2 from Red Hat. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 35% of all known vulnerabilities).
Official 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.
