Basic Interactive World Map <= 2.7 - Cross-Site Request Forgery to Settings Update

Description

The Basic Interactive World Map plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.7. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update plugin settings granted they can trick a site administrator into performing an action such as clicking on a link.
