## Description

The "gitDiff" function in Wayfair git-parse <=1.0.4 has a command injection vulnerability. Clients of the git-parse library are unlikely to be aware of this, so they might unwittingly write code that contains a vulnerability. The issue has been resolved in version 1.0.5.

## What to do

- Check your stack: if you ship or depend on n/a, git-parse, upgrade to a fixed version (1.0.5) per the references below.
