Admidio has IDOR in `documents-files.php` `mode=move_save` that lets any folder-uploader exfiltrate files from private folders
## Summary `modules/documents-files.php` gates state-changing modes by checking that the actor has `hasUploadRight()` on the URL parameter `folder_uuid`. The `move_save` handler then operates on a *separate* URL parameter `file_uuid` and calls `File::moveToFolder($destFolderUUID)`. `File::moveToFolder()` checks the upload right on the **destination...
