What the vulnerability does
The WP Global Screen Options plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.2. This is due to missing nonce validation on the `updatewpglobalscreenoptions` action handler. This makes it possible for unauthenticated attackers to modify global screen options for all users via a forged request granted they can trick an administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
WP Global Screen Options versions 0.2 and earlier are vulnerable to cross-site request forgery (CSRF). An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the site without the administrator's knowledge or consent. The vulnerability requires the administrator to visit the attacker's page while authenticated to WordPress.
What an attacker can do
Perform unwanted actions on the site by tricking an authenticated admin into visiting a malicious webpage.
Potential impact on your site
An attacker could modify site settings or perform administrative actions if an admin visits a malicious link while logged in.
Conditions required to exploit
Site admin must be logged into WordPress and visit an attacker-controlled page.
