The WP Custom Admin Login Page Logo plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.8.4. This is due to missing or incorrect nonce validation on the wpclpl_save functionality. 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.
