      "value": "The MailerPress – Email Marketing, Newsletter, Email Automation & WooCommerce Emails plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Campaign HTML Content Field in all versions up to, and including, 2.0.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The public-facing campaign preview endpoint (/mp-email/{id}-slug/) is not affected by this vulnerability, as it applies a Content-Security-Policy header blocking all inline scripts; exploitation is limited to the admin dashboard preview."

      "value": "El plugin MailerPress - Email Marketing, Newsletter, Email Automation & WooCommerce Emails para WordPress es vulnerable a cross-site scripting almacenado a través del campo de contenido HTML de campaña en todas las versiones hasta la 2.0.4, inclusive, debido a una sanitización de entrada y un escape de salida insuficientes. Esto hace posible que atacantes autenticados, con acceso de nivel de autor y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. El endpoint de vista previa de campaña de cara al público (/mp-email/{id}-slug/) no se ve afectado por esta vulnerabilidad, ya que aplica un encabezado Content-Security-Policy que bloquea todos los scripts en línea; la explotación se limita a la vista previa del panel de administración."
