How to fix?

There is no fixed version for node-import.

Overview

node-import is a package that imports dependencies and run it directly or concatenate them and exports to file.

Affected versions of this package are vulnerable to Arbitrary Code Execution. The "params" argument of module function can be controlled by users without any sanitization.b. This is then provided to the “eval” function located in line 79 in the index file "index.js".

PoC

var a = require("node-import");
var params = {
  'fs=require("fs");fs.writeFile("JHU");//':123
}
a.module('',params,true)
