This is due to insufficient input sanitization and output escaping on the author display name when no author URL is present. The plugin accesses `$draft_data->display_name` which, because `display_name` is not a native WP_Post property, triggers WP_Post::__get() and resolves to `get_post_meta($post_id, 'display_name', true)`. When the `user_url` meta field is empty, the `$author` value is assigned to `$author_link` on line 383 without any escaping (unlike line 378 which uses `esc_html()` for the `{{author}}` tag, and line 381 which uses `esc_html()` when a URL is present). This unescaped value is then inserted into the shortcode output via `str_replace()`. 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 a page containing the `[drafts]` shortcode with the `{{author+link}}` template tag."}, {"lang": "es", "value": "El plugin Simple Draft List para WordPress es vulnerable a cross-site scripting almacenado a trav\u00e9s del metadato de publicaci\u00f3n 'display_name' (Campo Personalizado) en todas las versiones hasta la 2.6.2 inclusive. Esto se debe a una sanitizaci\u00f3n de entrada y un escape de salida insuficientes en el nombre de visualizaci\u00f3n del autor cuando no hay una URL de autor presente. El plugin accede a `$draft_data->display_name` lo cual, debido a que `display_name` no es una propiedad nativa de WP_Post, activa WP_Post::__get() y se resuelve a `get_post_meta($post_id, 'display_name', true)`. Cuando el campo meta `user_url` est\u00e1 vac\u00edo, el valor de `$author` se asigna a `$author_link` en la l\u00ednea 383 sin ning\u00fan escape (a diferencia de la l\u00ednea 378 que usa `esc_html()` para la etiqueta `{{author}}`, y la l\u00ednea 381 que usa `esc_html()` cuando hay una URL presente). Este valor sin escape se inserta luego en la salida del shortcode a trav\u00e9s de `str_replace()`.
