Hi Paul,

The documentation you linked to was updated yesterday to reflect the issue
I brought up with cookie-stored sessions.

Again, the behavior is a surprise to most developers.


Thanks!

Perhaps next you will disclose that if an attacker obtains a user's
password, they can log in as that user. Seriously, "full disclosure"
of well documented behavior is not particularly impressive.

invalidation issue

FD,

I’m back!

Django versions 1.4 – 1.7 offer a cookie-based session storage option
(not the default > this time) that is afflicted by the same issue I posted
about previously concerning Ruby > on Rails:

If you obtain a user’s cookie, even if they log out, you can still log
in as them.

The short write-up is here, if needed:

Cheers,
