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) {
// ...
});
