      "value": "The Autoptimize plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ao_post_preload' meta value in all versions up to, and including, 3.1.14. This is due to insufficient input sanitization in the `ao_metabox_save()` function and missing output escaping when the value is rendered into a `<link>` tag in `autoptimizeImages.php`. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, granted the \"Image optimization\" or \"Lazy-load images\" setting is enabled in the plugin configuration."

      "value": "El plugin Autoptimize para WordPress es vulnerable a cross-site scripting almacenado a través del valor meta 'ao_post_preload' en todas las versiones hasta la 3.1.14, inclusive. Esto se debe a una sanitización de entrada insuficiente en la función `ao_metabox_save()` y a una falta de escape de salida cuando el valor se renderiza en una etiqueta `` en `autoptimizeImages.php`. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador o superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada, siempre que la configuración de \"Optimización de imágenes\" o \"Carga diferida de imágenes\" esté habilitada en la configuración del plugin."
