Overview

apache-airflow is a platform to programmatically author, schedule, and monitor workflows.

Affected versions of this package are vulnerable to Improper Authentication due to missing authentication in the variable import endpoint. This allowed unauthenticated users to add/modify Airflow variables used in DAGs, potentially resulting in a denial of service, information disclosure or remote code execution.
