Vulnerability Overview

The Complianz plugin for WordPress is vulnerable to Cross-Site Request Forgery to Stored Cross-Site Scripting in versions up to, and including, 6.4.5 (Free) and 6.4.7 (Premium). This is due to missing nonce validation on several functions called via AJAX actions such as cmplz_delete_cookiebanner(), cmplz_duplicate_cookiebanner(), maybe_install_suggested_plugins (), and ajax_create_pages() to list a few. This makes it possible for unauthenticated attackers to invoke these functions and perform multiple actions like deleting/duplicating cookie banners installing suggested plugins, creating pages, and more via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 6.4.8, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
