What is CVE-2026-96740?

A security flaw exists in the StreamsHub Console for Apache Kafka that permits the unauthorized manipulation of tenant-supplied Kafka client properties. When these properties are incorporated into the console-api AdminClient configuration without appropriate filtering of sensitive security keys, it creates an avenue for exploitation. Attackers can potentially extract the console-api ServiceAccount token by misconfiguring critical settings such as config.providers and bootstrap.servers, leading to a risk of sensitive information being exfiltrated to an unauthorized broker.
