Deployments that have enabled the Kafka event producer \u2014 `dag_run_events_enabled` or `task_instance_events_enabled`, both disabled by default \u2014 build that client inside the scheduler process, so a user whose only privilege is editing Airflow connections gains arbitrary code execution in the control plane; the Airflow security model limits connection-configuration users to code execution on workers, not the scheduler. Deployments using Google Managed Kafka are not affected, because that code path overwrites any user-supplied `oauth_cb`; plain brokers and Amazon MSK are exposed.
