info:
|
|
name: Apache Airflow <= 1.10.10 - 'Example Dag' Remote Code Execution
|
|
author: pdteam

severity: high
|
|
description: An issue was found in Apache Airflow versions 1.10.10 and below. A remote code/command injection vulnerability was discovered in one of the example DAGs shipped with Airflow which would allow any authenticated user to run arbitrary commands as the user running airflow worker/scheduler (depending on the executor in use). If you already have examples disabled by setting load_examples=False in the config then you are not vulnerable.
