CVE-2020-11978
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.
Summary dbcve.org
Apache Airflow versions 1.10.10 and below ship with example DAGs containing a command injection vulnerability. Any user authenticated to the Airflow web interface can craft requests through the vulnerable example DAG that execute arbitrary operating system commands on the host running the Airflow worker or scheduler process.
Mitigation
Set load_examples=False in the Airflow configuration to disable loading of example DAGs, or upgrade to a version beyond 1.10.10 that contains the patched example DAGs.
