*** This bug is a security vulnerability ***

Public security bug reported:

Impact
======
Saved passwords are accessible by HTTP sites in epiphany 3.18.10-0ubuntu1 for 
Ubuntu 16.04 LTS, 3.22.5-0ubuntu0.1 for 16.10 and older versions. This means 
that a man-in-the-middle fake version of a website could capture your password 
by presenting say a fake http://facebook.com/

This is made worse because Javascript can be used to collect filled-in
form data even if the user has not clicked Submit yet.

This is made worse because Epiphany doesn't yet respect the HSTS headers
which force sites that have opted in to be only available via HTTPS.

Test Case
=========

Regression Potential
====================
Low. The fix is to move all already saved passwords to be associated with 
https. Users will need to enter this password in again if the site is HTTP 
only. This is disruptive if the only place the user has saved the password is 
in Epiphany. Websites should allow password reset. However, both Firefox and 
Chrome as of January 2017 warn users before entering passwords for http sites. 
Epiphany 3.24 will add that warning in its March 2017 release.

Other Info
==========
Fixed upstream in 3.18.11 and 3.22.6:
