Title: Apache Airflow de Apache Software Foundation, Description: El decodificador de referencia de fecha límite del lado del programador de Apache Airflow ( SerializedCustomReference.deserialize_reference ) importaba y despachaba rutas de clase arbitrarias extraídas de un estado serializado controlado por el autor del DAG sin una lista de permitidos o una puerta de registro de plugins. Un autor de DAG cuyo código llega al programador - el valor predeterminado en implementaciones de un solo host donde el paquete DAG es importable desde el proceso del programador - podría incrustar una 'DeadlineReference' personalizada cuya forma serializada nombraba una ruta de módulo controlada por el atacante, haciendo que el programador  import_string(...)  e instancie esa clase con una sesión de SQLAlchemy activa adjunta. Afecta a las implementaciones donde el código del autor del DAG es menos confiable que el proceso del programador. Se aconseja a los usuarios actualizar a  apache-airflow  3.2.2 o posterior.

Apache Airflow's scheduler-side deadline-reference decoder (`SerializedCustomReference.deserialize_reference`) imported and dispatched arbitrary class paths drawn from DAG-author-controlled serialized state without an allowlist or plugin-registry gate. A DAG author whose code reaches the scheduler — the default on single-host deployments where the DAG bundle is importable from the scheduler process — could embed a custom `DeadlineReference` whose serialized form named an attacker-controlled module path, causing the scheduler to `import_string(...)` and instantiate that class with a live SQLAlchemy session attached. Affects deployments where DAG-author code is less trusted than the scheduler process. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.
