Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Pterodactyl Panel (Packagist pterodactyl/panel) before 1.12.3 and the Wings daemon (Go github.com/pterodactyl/wings) before 1.12.2 are affected. A subuser who has any server access, such as console connection or file or backup download, can reuse a panel-issued JWT meant for those actions to upload arbitrary files to the same server without the file.create permission. Upgrade the Panel to 1.12.3 and Wings to 1.12.2 or later.
