Description
The WebRequest API implementation in extensions/browser/api/web_request/web_request_api.cc in Google Chrome before 45.0.2454.85 does not properly consider a request's source before accepting the request, which allows remote attackers to bypass intended access restrictions via a crafted (1) app or (2) extension.
