GDPR CCPA Compliance & Cookie Consent Banner <= 2.7.0 - Missing Authorization to Settings Update and Stored Cross-Site Scripting

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.
