Cross-site request forgery (CSRF) vulnerability in the TweetScribe plugin 1.1 and earlier for WordPress allows remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the tweetscribe_username parameter in a save action in the tweetscribe.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.
