CVE-2021-26697 · Apache Airflow: Lineage API endpoint for Experimental API missed authentication check

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
