9.8 criticalEPSS 81%

Critical (9.8) in apache airflow. EPSS 81% chance of exploitation in the next 30 days. Fixed in apache-airflow 2.1.3.

The variable import endpoint was not protected by authentication in Airflow >=2.0.0, <2.1.3. This allowed unauthenticated users to hit that endpoint to add/modify Airflow variables used in DAGs, potentially resulting in a denial of service, information disclosure or remote code execution. This issue affects Apache Airflow >=2.0.0, <2.1.3.
