AI-suggested
Users should upgrade Apache Airflow to version 3.4.0 or later, where the CeleryExecutor worker validates authentication tokens before executing callbacks. This official fix prevents unauthorized execution of callback workloads. Until upgraded, deployments remain vulnerable if the Celery broker is accessible for unauthorized writes.
Description
Apache Airflow's CeleryExecutor component allowed execution of callback workloads without validating authentication tokens. This flaw enables an attacker with write access to the Celery broker to enqueue forged callbacks that execute arbitrary code on all CeleryExecutor workers without needing Airflow credentials. The issue affects deployments using the CeleryExecutor. A fix is available in Apache Airflow version 3.4.0 and later, where token validation is enforced before executing callbacks.
