Cross-site request forgery (CSRF) vulnerability in the Portfolio plugin before 1.05 for WordPress allows remote attackers to hijack the authentication of administrators for requests that have unspecified impact via a request to the instagram-portfolio page in 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.
