4Description
The Complianz - GDPR/CCPA Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 7.4.4.2.

This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the injected page. The Classic Editor plugin is required to be installed and activated in order to exploit this vulnerability.
