The GDPR CCPA Compliance & Cookie Consent Banner plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions named ajaxUpdateSettings() in all versions up to, and including, 2.7.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the plugin's settings, update page content, send arbitrary emails and inject malicious web scripts.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
