The Custom Product List Table plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.0.0. This is due to missing or incorrect nonce validation when modifying products. This makes it possible for unauthenticated attackers to add, delete, bulk edit, approve or cancel products via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
CWE-352
