The fix

We hold no Microsoft remediation data for CVE-2026-83561, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

The Complianz GDPR/CCPA Cookie Consent Banner plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via Elementor Cookie Blocker Regex in all versions up to, and including, 7.5.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires an administrator to approve the attacker's comment, and the site must have both the Elementor plugin installed and Complianz configured with the Twitter or Facebook cookie/script blocker enabled.
