Descriptions

The lineage endpoint of the deprecated Experimental API was not protected by authentication in Airflow 2.0.0. This allowed unauthenticated users to hit that endpoint. This is low-severity issue as the attacker needs to be aware of certain parameters to pass to that endpoint and even after can just get some metadata about a DAG and a Task. This issue affects Apache Airflow 2.0.0.

El endpoint lineage de la API Experimental obsoleta no estaba protegido por autenticación en Airflow versión 2.0.0. Esto permitió a usuarios no autenticados llegar a ese endpoint. Este es un problema de baja gravedad, ya que el atacante debe estar consciente de determinados parámetros para pasar a ese endpoint e incluso después puede obtener algunos metadatos sobre un DAG y una tarea. Este problema afecta a Apache Airflow versión 2.0.0

*Credits: Apache Airflow would like to thank Ian Carroll for reporting this issue.
