    npm install simple-git@3.5.0

Technical details

The simple-git library before version 3.5.0 is vulnerable to command injection (specifically argument injection, CWE-88). This occurs because the library fails to properly sanitize or block the '--upload-pack' argument when executing 'git clone' operations. While a previous fix (CVE-2022-24433) addressed this for 'git fetch', the 'git clone' vector remained open. An attacker can provide a malicious URL or argument list containing '--upload-pack' followed by arbitrary shell commands, which Git then executes. This can be exploited remotely if the application accepts user-supplied repository URLs. The vulnerability is fixed in version 3.5.0.
