Multiple cross-site request forgery (CSRF) vulnerabilities in the DandyID Services plugin 1.5.9 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) email_address or (2) sidebarTitle parameter in the dandyid-services.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.
