Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 improperly control the ability of a web worker to create a WebSocket object, which allows remote attackers to bypass intended mixed-content restrictions via crafted JavaScript code.
