Vulnerability Overview

The Theme Changer plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4. This is due to missing or incorrect nonce validation on the theme_changer_options() function. This makes it possible for unauthenticated attackers to update the 'theme_changer_password' option value granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 1.5, 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.
