Summary
url-parse Incorrectly parses URLs that include an '@'
Details

A specially crafted URL with an '@' sign but empty user info and no hostname, when parsed with url-parse, url-parse will return the incorrect href. In particular,

js parse(\"http://@/127.0.0.1\") Will return: yaml { slashes: true, protocol: 'http:', hash: '', query: '', pathname: '/127.0.0.1', auth: '', host: '', port: '', hostname: '', password: '', username: '', origin: 'null', href: 'http:///127.0.0.1' } If the 'hostname' or 'origin' attributes of the output from url-parse are used in security decisions and the final 'href' attribute of the output is then used to make a request, the decision may be incorrect.
