CVE-2025-13144

The ContentStudio plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3.7. This is due to missing or insufficient nonce validation on the add_cstu_settings function. This makes it possible for unauthenticated attackers to modify plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
