Recommended response

Check inventory. Check lockfiles and deployed manifests for Red Hat/console-operator.
Review the reported fix. Source-reported workaround: Restrict `create`, `update`, and `patch` permissions for Console custom resources to trusted administrators only. Where supported, apply a NetworkPolicy to restrict Console API egress to approved Kafka broker endpoints. These controls reduce exposure to the reported ServiceAccount-credential disclosure path but do not replace the permanent fix, which is to filter security-sensitive Kafka client properties. Upgrade to a release containing the permanent fix when available.

Sources and claim methodology

Upstream source 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.
