Hi,
I created a user form for changing e-mail address, but I'm able to see and change e-mail address of another user when I just change user_id in url.
/account/?layout_id=71&user_id=7
/account/?layout_id=71&user_id=8
/account/?layout_id=71&user_id=9
Only user who is logged-in.
This is "my account" changing e-mail form.
But if logged-in user with author role, can change e-mails of another author user just with change user_id in url, it mean that something is wrong.
