details: 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.
