CVE-2026-3339

Estado: AplazadaBaja (2.7)—

The Keep Backup Daily plugin for WordPress is vulnerable to Limited Path Traversal in all versions up to, and including, 2.1.1 via the `kbd_open_upload_dir` AJAX action. This is due to insufficient validation of the `kbd_path` parameter, which is only sanitized with `sanitize_text_field()` - a function that does not strip path traversal sequences. This makes it possible for authenticated attackers, with Administrator-level access and above, to list the contents of arbitrary directories on the server outside of the intended uploads directory.

Esto se debe a una validación insuficiente del parámetro 'kbd_path', que solo se sanea con 'sanitize_text_field()', una función que no elimina secuencias de salto de ruta. Esto hace posible que atacantes autenticados, con acceso de nivel de Administrador y superior, listen el contenido de directorios arbitrarios en el servidor fuera del directorio de subidas previsto."
