Quick fix

PYSEC-2021-122 — apache-airflow: upgrade to the fixed version with the command below.

pip install --upgrade 'apache-airflow>=2.1.2'

Details

If remote logging is not used, the worker (in the case of CeleryExecutor) or the scheduler (in the case of LocalExecutor) runs a Flask logging server and is listening on a specific port and also binds on 0.0.0.0 by default. This logging server had no authentication and allows reading log files of DAG jobs. This issue affects Apache Airflow < 2.1.2.
