Description Prasad Pandit 2015-09-23 11:30:17 UTC

Security researcher Juho Nurminen reported a mechanism to spoof the
URL displayed in the addressbar in reader mode by manipulating the loaded
URL. This flaw allows for the URL displayed to be different than that the web
content rendered. This allows for potential spoofing but the effects are
mitigated due to the restrictions reader mode places when rendering content.
