Private wiki content could be extracted.
Yep! Still can on some browsers.
Articles could be edited in your name.
I thought
http://www.mediawiki.org/wiki/Manual:Edit_token protects
against this as it is required for an edit:

Yes. Except you can get tokens by the api. If we didn't drop permissions
to anon and reject requests for tokens to JSONP then it would be possible
for a 3rd party website to use JSONP to extract an edit token, and then
initiate a background iframe form POST to make an edit under your account.
And up till
recently it would have also been possible to make some
preferences changes that would effectively let someone take over your
whole account.
I didn't know OptionsToken is new
http://www.mediawiki.org/wiki/API:Options :-(
Cool! Learn something new about mediawiki every day.
Take care,
