Security: Google Chrome allows user to load phishing URL without any security warnings.

Reported by ja...@supmenow.com, Sep 14 2016

Issue description

Please see the following link for instructions on filing security bugs:
http://www.chromium.org/Home/chromium-security/reporting-security-bugs

NOTE: Security bugs are normally made public once a fix has been widely
deployed.

VULNERABILITY DETAILS

The Google Chrome Browser is able to load a spoofed Base 64 URL that when loaded, can load a remote webpage into the browser which harvests passwords.
I have attached the screenshot of this page and a text file including the link.

The browser fails to warn the user they have just loaded a base 64 file, and so the user could be fooled into entering in their credentials.
This is usually sent as an attachment in email and I have just fallen foul of this. 

The UI additionally doesn't highlight clearly that it isn't secure unless you bother to click for more details.

In the Base 64 URL the google URL is included to further confuse the user into thinking its the legitimate site.


VERSION
Chrome Version: 52.0.2743.116 + stable
Operating System: OS X 10.11.6

REPRODUCTION CASE
Follow the link attached in the text file to see how a user can load a phishing website via a base 64 link and chrome fails to warn about this.

Hello,

Mike/Charlie/Nick, could one of you please help with further triage/validation of this security ticket?  Or help reassign to an appropriate person?

Feel free to adjust the labels.  I wasn't sure if this should go under URL spoofing or safebrowsing.

Many thanks!

Adding meacer@, who is planning on disabling top-level navigations to data: URLs in some cases.

Yes. Loading `data:` URLs can be confusing, and I do think folks are poking at changing our behavior there (at least for forced navigation). Poking meacer@ again. ;)
