CVE-2026-7542

Estado: AplazadaMedia (6.5)—

The Slider Revolution plugin for WordPress is vulnerable to Sensitive Information Disclosure in versions 7.0 to 7.0.10. This is due to three compounding design flaws: (1) the plugin leaks a valid backend AJAX nonce (revslider_actions) to all authenticated users including Subscribers via the admin_footer hook; (2) the wordpress.create.image_from_url action is explicitly allowlisted in the $user_allowed array, bypassing the administrator-only access control; (3) the create_wordpress_image_from_url() function accepts an attacker-controlled url parameter that is passed to import_media(), where path_or_url_exists() explicitly accepts local filesystem paths (file_exists() && is_readable()) with no restriction to remote HTTP/HTTPS URLs, and @copy() physically copies those files into the publicly accessible /wp-content/uploads/revslider/ai/ directory. The MIME type check trusts the attacker-supplied content_type parameter to derive the destination extension without verifying actual file content, and the source extension blacklist does not block many sensitive types (.sql, .log, .json, .bak, .xml, .csv, .conf, .yml, .yaml, .pem, .key, .crt, .txt, .db, etc.). This makes it possible for authenticated attackers with Subscriber-level access and above to read the contents of server files with non-blacklisted extensions by having them copied to a publicly accessible URL.

      "value": "El plugin Slider Revolution para WordPress es vulnerable a la revelación de información sensible en versiones hasta la 7.0.10 inclusive. Esto se debe a tres fallos de diseño combinados: (1) el plugin filtra un nonce AJAX de backend válido (revslider_actions) a todos los usuarios autenticados, incluidos los Suscriptores, a través del hook admin_footer; (2) la acción wordpress.create.image_from_url está explícitamente en la lista blanca en el array $user_allowed, eludiendo el control de acceso exclusivo para administradores; (3) la función create_wordpress_image_from_url() acepta un parámetro url controlado por el atacante que se pasa a import_media(), donde path_or_url_exists() acepta explícitamente rutas de sistema de archivos locales (file_exists() && is_readable()) sin restricción a URLs HTTP/HTTPS remotas, y @copy() copia físicamente esos archivos en el directorio /wp-content/uploads/revslider/ai/ de acceso público. La verificación del tipo MIME confía en el parámetro content_type proporcionado por el atacante para derivar la extensión de destino sin verificar el contenido real del archivo, y la lista negra de extensiones de origen no bloquea muchos tipos sensibles (.sql, .log, .json, .bak, .xml, .csv, .conf, .yml, .yaml, .pem, .key, .crt, .txt, .db, etc.). Esto hace posible que los atacantes autenticados con acceso de nivel de Suscriptor y superior lean el contenido de archivos del servidor con extensiones no incluidas en la lista negra al hacer que se copien a una URL de acceso público."
