CVE-2026-54593

Pterodactyl's improper JWT scoping allows subuser to upload files when not explicitly granted `file.create` permissions

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.
