Comment (by nomanriffat):

 Thought about it again and realized this is still not robust solution. For
 example an attacker can open iframe and crawl into its DOM and submit
 form. There is a solution for it too i.e. set X-Frame-Options to deny on
 even same-origin.


 2nd use case is that an attacker can open child window and walk into its
 DOM and submit form. I don't find any technique to disable Javascript to
 get executed from parent window into child window. If someone can overcome
 this then we can have a robust solution.
