CVE-2021-26697

5.3 mediumEPSS 4.6%

Medium (5.3) in apache airflow. EPSS 4.6% chance of exploitation in the next 30 days. Fixed in apache-airflow 2.0.1, 2.0.1rc1.

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.
