CVE-2021-26697Apache Airflow: Lineage API endpoint for Experimental API missed authentication check
Medium 5.3
In plain English
A medium-severity privilege mismanagement in Apache Airflow from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 4.6% (higher than 92% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
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.
