Affected packages
• npm ps-kill: <= 1.0.0 (no fix yet)
Description
This affects all versions of package ps-kill. 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 in the index.js file.
PoC (provided by reporter):
```js
var ps_kill = require('ps-kill');
ps_kill.kill('$(touch success)', function() {});
```
