David Kierznowski has reported a vulnerability in FeedBurner
FeedSmith, which can be exploited by malicious people to conduct
cross-site request forgery attacks.

perform certain actions via HTTP requests without performing any
validity checks to verify the request. This can be exploited to
change certain settings and e.g. hijack blog feeds.

be affected.
