This is like saying every app on the internet is vulnerable to authentication hijacking, because if I take your username and your password then I can login as you!  

This is not the same. Cookies can be linked with unique secret tokens stored
in POST hidden fields (that are unique per every browser) and its IP address, 
therefore just copying of the cookie to the different browsers won't work
at all.
