I'm not sure how big of a deal this is. I mean... the entire document is unclassified. It's not even at the "secret" level. Do we know if this is a leak, or if it was just.. published.
I don't think this is a big deal at all. It is unclassified and also not marked with one of the Sensitive But Unclassified markings (http://en.wikipedia.org/wiki/Sensitive_but_unclassified) meant to control distribution. You could request this document through a freedom of information act request.
not every document which doesn't have SECRET stamp on it is intended for public eye...
