How to fix?
There is no fixed version for props.
Overview
props is an extract json/yaml from the beginning of text files
Affected versions of this package are vulnerable to Command Injection due to Unsafe Deserialization in props module.
The module uses yaml-js.load() function to load a YAML file without any validation/sanitization.
If an attacker can control the YAML file, it could run arbitrary JavaScript code on the victim machine.
