CVE-2022-24066 Open this link in a new tabHow to fix?
Upgrade simple-git to version 3.5.0 or higher.
Overview
simple-git is a light weight interface for running git commands in any node.js application.
Affected versions of this package are vulnerable to Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') due to an incomplete fix of CVE-2022-24433 which only patches against the git fetch attack vector.
A similar use of the --upload-pack feature of git is also supported for git clone, which the prior fix didn't cover.
PoC
const simpleGit = require('simple-git')
const git2 = simpleGit()
git2.clone('file:///tmp/zero123', '/tmp/example-new-repo', ['--upload-pack=touch /tmp/pwn']);
