      "value": "The WP Statistics – Simple, privacy-friendly Google Analytics alternative plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'utm_campaign' parameter in all versions up to, and including, 14.16.8 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. The payload can be planted without authentication via the public /wp-statistics/v2/hit REST endpoint, because the required signature is exposed on the public homepage and a base64-encoded page_uri POST parameter overrides the previously sanitized REQUEST_URI, allowing the malicious utm_campaign value to bypass sanitization and be stored in the database."

      "value": "El plugin WP Statistics - Alternativa a Google Analytics simple y respetuosa con la privacidad para WordPress es vulnerable a Cross-Site Scripting Almacenado a través del parámetro ’utm_campaign’ en todas las versiones hasta la 14.16.8, inclusive, debido a una sanitización de entrada y escape de salida insuficientes. Esto hace posible que atacantes no autenticados inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. La carga útil puede ser plantada sin autenticación a través del endpoint REST público /wp-statistics/v2/hit, porque la firma requerida está expuesta en la página de inicio pública y un parámetro POST page_uri codificado en base64 anula el REQUEST_URI previamente sanitizado, permitiendo que el valor malicioso de utm_campaign omita la sanitización y sea almacenado en la base de datos."
