How to fix?

There is no fixed version for portkiller.

Overview

portkiller is a port killer.

Affected versions of this package are vulnerable to Arbitrary Command Injection. If (attacker-controlled) user input is given, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization.

PoC (provided by reporter):

var portkiller = require('portkiller');

portkiller('$(touch success)');

(A file called success will be created as a result of the execution of touch success.)
