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.
