Overview

Affected versions of this package are vulnerable to Information Exposure. The importScripts function in the Web Workers API implementation in Mozilla Firefox before 43.0 allows remote attackers to bypass the Same Origin Policy by triggering use of the no-cors mode in the fetch API to attempt resource access that throws an exception, leading to information disclosure after a rethrow.
