Description

The vulnerability allows a remote attacker to perform CSRF attacks.

The vulnerability exists due to improper validation of the HTTP request origin within "wp-admin/includes/class-wp-screen.php" and "wp-admin/widgets.php" scripts. A remote attacker can create a specially specially crafted web page, trick the authenticated victim into visiting it, perform cross-site request forgery attack and hijack the authentication of unspecified victims for requests that perform a widgets-access action.

Successful exploitation of the vulnerability may allow an attacker to bypass authentication.
