## Overview

### Impact
It is possible to run arbitrary commands through the yaml.load() method.  This could allow an attacker with local access to the host to run arbitrary code by running the application with a specially crafted YAML configuration file.

### Workarounds
Manually adjust yaml.load() to yaml.safe_load()
