Multiple cross-site request forgery (CSRF) vulnerabilities in the Wp Unique Article Header Image plugin 1.0 and earlier for WordPress allow remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the (1) gt_default_header or (2) gt_homepage_header parameter in the wp-unique-header.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.
