CVE-2026-96740: Red Hat Streams For Apache Kafka 2

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
