Vulnerability in Complianz GDPR/CCPA Cookie Consent Banner — CVE-2026-83561

What to do now

Update Complianz GDPR/CCPA Cookie Consent Banner to 7.5.5 or later.

Affected versions

• Everything up to and including 7.5.4

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.
