Una vulnerabilidad de tipo Cross-Site Scripting (XSS) no autenticado en el plugin Age Gate de Phil Baker versiones anteriores a 2.17.0 incluyéndola, en WordPress

The Age Gate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via data imports in versions up to, and including, 2.17.0 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.
