iThoughts Advanced Code Editor <= 1.2.10 - Cross-Site Request Forgery to Settings Update

Description

The iThoughts Advanced Code Editor plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2.10. This is due to missing or incorrect nonce validation on the 'ithoughts_ace_update_options' AJAX action. This makes it possible for unauthenticated attackers to update plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
