CVE-2017-20146 Open this link in a new tabHow to fix?
Upgrade github.com/gorilla/handlers to version 1.3.0 or higher.
Overview
github.com/gorilla/handlers is a collection of handlers (aka "HTTP middleware") for use with Go's net/http package (or any framework supporting http.Handler).
Affected versions of this package are vulnerable to Improper Access Control. CORS is misconfigured to allow the server to reflect all origin headers. This may allow an attacker to make AJAX requests to vulnerable hosts through cross-site scripting or a malicious HTML Document, effectively bypassing the Same Origin Policy.
