It looks like the email I'm responding to never made it to the users or dev 
list; and it was lost in moderation in the infra list. Given the important of 
the topic, I'm responding anyway, including the users list.

When you install Jenkins, it doesn't set up access control automatically. 
You're expected to do this afterwards (which has its problems[1], but that's 
the way it is right now). Jenkins even tells you to do that on the "Manage 
Jenkins" screen if security has not been set up.

And when on the "Configure Global Security" page, one of the options is a 
checkbox that says "Prevent Cross Site Request Forgery exploits". Its help text 
basically explains why it's not enabled by default:

I tested a few of the examples provided, and none worked when I enabled this 
protection. I really doubt any of them work.

So, don't just install and start Jenkins, and then go home. Set it up properly, 
and you're safe.
