```php
if ( is_admin() ) {
    add_action( 'admin_enqueue_scripts', 'p3dlite_enqueue_scripts_backend' );
    add_action( 'wp_ajax_p3dlite_handle_upload', 'p3dlite_handle_upload' );
    add_action( 'wp_ajax_nopriv_p3dlite_handle_upload', 'p3dlite_handle_upload' );
    include 'includes/3dprint-lite-admin.php';
}
else {
    add_action( 'wp_enqueue_scripts', 'p3dlite_enqueue_scripts_frontend' );
    include 'includes/3dprint-lite-frontend.php';
}
```

跟踪 p3dlite\_handle\_upload 方法 `wp-content/plugins/3dprint-lite/includes/3dprint-lite-functions.php`

向下看可以看到一个标准的文件上传代码

通过调试可以找到上传路径 `/wp-content/uploads/p3d/`

未授权调用 p3dlite\_handle\_upload 上传文件
