Description
The iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via AdSense Regex Rewrite in all versions up to, and including, 3.13.4 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. This vulnerability only manifests when the 'Secondary' parser engine is active (parser_engine=default); it does not exist under the default 'new' DOM-based parser engine.
