Download IP2Location Country Blocker < 2.34.3 - Cross-Site Request Forgery

Description

The Download IP2Location Country Blocker plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.34.2. This is due to missing or incorrect nonce validation on the validate_api_key() function. This makes it possible for unauthenticated attackers to replace the API key via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
