Input validation vulnerability in Auto Publish for Google My Business 3.8

The Auto Publish for Google My Business plugin for WordPress has a security vulnerability that affects all versions up to and including 3.7. This means that unauthenticated attackers can potentially manipulate the system without needing a password. For example, they may be able to automatically post to Google, delete saved data, or change post information if they can get a site administrator to click on a malicious link. This vulnerability happens because the plugin does not have sufficient security checks in place.
