AV:N/AC:M/AU:N/C:N/I:P/A:N

WebKit/Source/core/css/StyleSheetContents.cpp in Blink, as used in Google Chrome before 51.0.2704.63, permits cross-origin loading of CSS stylesheets by a ServiceWorker even when the stylesheet download has an incorrect MIME type, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.
