CVE-2021-4394

Locations <= 3.2.1 - Cross-Site Request Forgery Bypass

The Locations plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.2.1. This is due to missing or incorrect nonce validation on the saveCustomFields() function. This makes it possible for unauthenticated attackers to update custom field meta data via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
