Summary

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.

Risk Assessment

An organization using this plugin may suffer session hijacking or malicious code execution in visitors' browsers, leading to data theft and unauthorized actions.

Recommendation

Update the Complianz plugin to a version later than 7.5.4, or if not possible, disable the Twitter/Facebook cookie blockers or restrict comment approval to trusted authors.
