Facebook for WordPress <= 3.0.3 - Cross-site Request Forgery to Stored Cross-site Scripting and Settings Deletion via wp_ajax_(save|delete)_fbe_settings

The wp_ajax_save_fbe_settings and wp_ajax_delete_fbe_settings AJAX actions of the Facebook for WordPress plugin before 3.0.4 were vulnerable to CSRF due to a lack of nonce protection. The settings in the saveFbeSettings function had no sanitization allowing for script tags to be saved.
