*Description*: 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*. *Credit*: Apache Airflow would like to thank Nathan Jones, National Australia Bank’s Offensive Security Team
