Vulnerability Overview

The WP Meta SEO plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.4.8. This is due to incorrect nonce validation which only verifies the presence of a nonce value rather than the on the validity of the nonce on a couple of cases in the loadPage() function. This makes it possible for unauthenticated attackers to modify the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 4.4.9, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) 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.
