How to fix?

Upgrade git-ls-remote to version 0.2.0 or higher.

Overview

git-ls-remote is an npm package used for listing references in a remote git repository. Vulnerable versions of the package pass the git url argument to the exec function without sanitisation. An attacker can use this to inject malicious shell commands to disrupt server operation or obtain sensitive information.

Example

var git = require('git-ls-remote');
git.head('https://gitrepo.com/; cat /etc/passwd', function(err, result) {
  // ...
});
