Machine-written summary

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

Pterodactyl Panel versions before 1.12.1 let a Wings node that holds a valid node access token read configuration data for servers on other nodes, including install scripts that may contain secret values. The same node can also change the installation or transfer status of those servers, and a false transfer success can cause the panel to delete a server from its source node. Upgrade to Pterodactyl Panel 1.12.1 or later. The source gives no workaround beyond upgrading.
