Summary
The LEAV Last Email Address Validator plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions <= 1.7.1. This is due to missing or incorrect nonce validation on the display_settings_page function. This makes it possible for unauthenticated attackers to modify plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
