Complianz vulnerabilities

The Complianz GDPR/CCPA Cookie Consent Banner plugin for WordPress (versions up to and including 7.5.5) is vulnerable to stored Cross-Site Scripting (XSS) via comment content and the yotu-wp Cookie-Blocker filter due to insufficient input sanitization and output escaping. An unauthenticated attacker can inject arbitrary web scripts into pages that execute when a user accesses the injected page.

The Complianz plugin versions 7.5.0 and earlier are vulnerable to unauthenticated sensitive data exposure. Unauthenticated attackers can access confidential information.

The Complianz plugin versions up to 7.5.0 contain a PHP Object Injection vulnerability exploitable by an administrator. An attacker with admin privileges can inject a malicious PHP object.

The Complianz plugin versions 7.5.0 and earlier have a Server-Side Request Forgery (SSRF) vulnerability exploitable by an author. A user with author role can force the server to send requests to internal resources.
