The Cookie Banner for GDPR / CCPA – WPLP Cookie Consent plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.3.7. This is due to missing or incorrect nonce validation on the process_bulk_action function. This makes it possible for unauthenticated attackers to permanently delete or forcibly resolve arbitrary GDPR data request records stored in the wpl_data_req table via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
