What the vulnerability does
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.

The vulnerability requires user interaction—the victim must visit the attacker's page—and does not expose sensitive data, but can modify site settings or data.
What an attacker can do
