Descriptions

Apache Airflow, versions before 2.8.1, have a vulnerability that allows a potential attacker to poison the XCom data by bypassing the protection of "enable_xcom_pickling=False" configuration setting resulting in poisoned data after XCom deserialization. This vulnerability is considered low since it requires a DAG author to exploit it. Users are recommended to upgrade to version 2.8.1 or later, which fixes this issue.

Apache Airflow, versiones anteriores a 2.8.1, tienen una vulnerabilidad que permite a un atacante potencial envenenar los datos de XCom al evadir la protección de la configuración "enable_xcom_pickling=False", lo que genera datos envenenados después de la deserialización de XCom. Esta vulnerabilidad se considera baja ya que requiere un autor de DAG para explotarla. Se recomienda a los usuarios actualizar a la versión 2.8.1 o posterior, que soluciona este problema.
