name: Apache Airflow <=1.10.10 - Remote Code Execution
2021-06-03 08:27:09 +00:00
author: pdteam
severity: high
description: Apache Airflow versions 1.10.10 and below are vulnerable to remote code/command injection vulnerabilities in one of the example DAGs shipped with Airflow. This could allow any authenticated user to run arbitrary commands as the user running airflow worker/scheduler (depending on the executor in use).
