URL Confusion When Scheme Not Supplied in medialize/uri.js

Description

Medialize is a Javascript URL mutation library. When parsing a URL without a scheme and with excessive slashes, like ///www.example.com, URI.js will parse the hostname as null and the path as /www.example.com. Such behaviour is different from that exhibited by browsers, which will parse ///www.example.com as http://www.example.com instead.

Recommendation

Update the urijs package to the latest compatible version. Followings are version details:

• Affected version(s): < 1.19.11
• Patched version(s): 1.19.11
