[Jarek Potiuk <potiuk () apache org>]

Description:

Improper Neutralization of Special Elements used in an OS Command ('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 install the Spark Provider version 4.0.0 in order to get rid of the 
vulnerability on top of Airflow 2.3.0+ version that has lower version of the Spark Provider installed).
