      "value": "Pterodactyl is a free, open-source game server management panel. Prior to Panel version 1.12.3 and Wings version 1.12.2, the Wings /upload/file endpoint accepted any valid panel-signed JWT that contained server_uuid, user_uuid, and unique_id claims without checking the token's intended purpose; because the Panel issues JWTs carrying those same claims for lower-privilege operations such as WebSocket authentication and file-download links, an authenticated subuser could reuse one of those tokens (for example a WebSocket token obtained with only the websocket.connect permission) by replaying it against /upload/file to write arbitrary files to the same server, despite never being granted the file.create permission. This issue is fixed in Panel version 1.12.3 and Wings version 1.12.2."

      "value": "Pterodactyl es un panel de gestión de servidores de juegos gratuito y de código abierto. Antes de la versión 1.12.3 del Panel y la versión 1.12.2 de Wings, el endpoint /upload/file de Wings aceptaba cualquier JWT válido firmado por el panel que contenía las claims server_uuid, user_uuid y unique_id sin verificar el propósito previsto del token; porque el Panel emite JWTs que contienen esas mismas claims para operaciones de menor privilegio, como la autenticación de WebSocket y los enlaces de descarga de archivos, un subusuario autenticado podía reutilizar uno de esos tokens (por ejemplo, un token de WebSocket obtenido solo con el permiso websocket.connect) al reproducirlo contra /upload/file para escribir archivos arbitrarios en el mismo servidor, a pesar de que nunca se le concedió el permiso file.create. Este problema está solucionado en la versión 1.12.3 del Panel y la versión 1.12.2 de Wings."
