Descriptions

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.

La función importScripts en la implementación API Web Workers en Mozilla Firefox en versiones anteriores a 43.0 permite a atacantes remotos eludir la Same Origin Policy desencadenando el uso del modo no-cors en la API fetch para intentar acceder a los recursos que producen una excepción, dando lugar a la divulgación de información después de un volver a lanzar.
