How to fix?

There is no fixed version for psnode.

Overview

psnode is an A Node.js KISS module to list and kill process on OSX and Windows.

Affected versions of this package are vulnerable to Arbitrary Command Injection. If attacker-controlled user input is given to the kill function, 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 psnode = require('psnode');
psnode.kill('$(touch success)', function() {});

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