CVE-2022-40954: Apache Airflow Spark Provider, Apache Airflow:
Airflow 2.3.4 spark provider RCE that bypass restrictions to read
arbitrary files
Description:

('OS Command Injection') vulnerability in Apache Airflow Spark
Provider, Apache Airflow allows an attacker to read arbtrary files
in the task execution context, without write access to DAG files.
This issue affects Spark Provider versions prior to 4.0.0. It
also impacts any Apache Airflow versions prior to 2.3.0 in
case Spark Provider is installed (Spark Provider 4.0.0 can only
be installed for Airflow 2.3.0+). Note that you need to manually
