Cross-site request forgery (CSRF) vulnerability in the FeedBurner FeedSmith 2.2 plugin for WordPress allows remote attackers to change settings and hijack blog feeds via a request to wp-admin/options-general.php that submits parameter values to FeedBurner_FeedSmith_Plugin.php, as demonstrated by the (1) feedburner_url and (2) feedburner_comments_url parameters.
