I have a problem in a Ruby on Rails app that I am working on. I have been working on the app for months and I have never had this problem before and after a bit of Google searches I think that somehow someone is trying to steal cookies with javascript.

When I click on the link I get an alert box titled "the page at www.napkinboard.com says:" and contains the following message:

__utmz=217223433.1270652009.59.3.utmcsr=localhost:3000|utmccn=(referral)|utmcmd=referral|utmcct=/; __utma=217223433.2133018314.1265749085.1271097412.1271125626.63; __utmc=217223433; __utmb=217223433.11.10.1271125626

I checked the database and all data associated with this 'food_item' looks completely normal and does not contain any javascript at all.

How did this suddenly happen and how can I stop it? I appreciate any help. Thanks.
