Severity ?
5.3 (Medium) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Summary
The Content Security Policy (CSP) implementation in Blink, as used in Google Chrome before 49.0.2623.75, does not ignore a URL's path component in the case of a ServiceWorker fetch, which allows remote attackers to obtain sensitive information about visited web pages by reading CSP violation reports, related to FrameFetchContext.cpp and ResourceFetcher.cpp.
