Cross-site request forgery (CSRF) vulnerability in the Twitter LiveBlog plugin 1.1.2 and earlier for WordPress allows remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the mashtlb_twitter_username parameter in the twitter-liveblog.php page to wp-admin/options-general.php.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
