How did I get logged in on to another person´s fastcupid.com account?

I was looking at fastcupid.com (that´s why the anon), trying to see if there were any promising MOTAS so I can know if I should bother signing up. I can´t do much not being a member, can´t see much on searches, free membership is offered to me. At the same time I´m also using other firefox tabs. I tab back to the fastcupid.com site and see that I´m logged in as a paid ´gold member´, a man at a city far from mine. I can see his private messages to and from members, when his membership expires, the last four digits of his credit card number, all the things that a man should only see if he logs in himself.

How could this have happened? No one else has had access to this computer, bought new at a reputable store.

Is there a security problem with my computer I need to fix? I´m running linux off the shelf on an Eee PC, encrypted wirelesss network to my own DSL connection.

What should I do, if anything? I know I can delete cookies and this account won´t come up, but is it a symptom of a bigger problem?

My speculation would be that it's a serious flaw in fastcupid's session management an that they assigned you the session id of an existing session.

If I had the experience you describe, I would have no worries that it represented a problem with my own computer (I say this is a moderately paranoid web programmer.)

Seconding Zed_Lopez. And in all likelihood they were scrambling to fix the problem as you experienced so you're unlikely to see it recur.

Having said that it would be kind of you to report it as they _may_ not know it's happening and it's just possible your report will reach the ears of someone who understands the significance of what you're telling them.

How are you connecting to the Web? At work? Your company might have some weird caching going on. At my last company, everyone suddenly found themselves with access to my GameSpot.com account.

Hm. How recently? "New" doesn't mean someone didn't log in to check their fastcupid mail or whatever, once?

Without deleting the cookie, check the date it was last set/changed. That will help.

CPB's guess is also good if this was done from work (or an internet cafe). Is this an HTTPS connection?

This could very easily have been the result of poorly-configured ISP caching. Using HTTPS should in theory eliminate the possibility of it recurring.

I have seen the same thing as Z_L is describing, that their session managemnet is awry. Imagine you went to a deli, and you had to take a ticket and wait in a queue. But, their ticket machine is not programmed right, and sometimes it gives 2 people the same number. Well, then when they call your number, you might get another man's meat.

Which is what is happening here, no?

And, as southof40 says - if I were responsible for this site, I'd appreciate an email...

As both a member of a fastcupid site and a web devloper, it doesn't shock me to hear that. The site barely works as on good days. It's most likely the result of sloppy session handling.
