AI-suggested

Users should upgrade to Apache Airflow version 3.4.0 or later, where the vulnerability is fixed by enforcing authentication token validation for callback workloads. No other mitigations are indicated by the vendor advisory.

Description

Apache Airflow versions prior to 3.4.0 using the CeleryExecutor are vulnerable to missing authentication for critical callback workloads. The CeleryExecutor runs callback workloads without validating authentication tokens, allowing attackers with write access to the Celery broker to enqueue forged callbacks that execute arbitrary code on all CeleryExecutor workers without credentials. This vulnerability is fixed in Apache Airflow 3.4.0 and later.
