GHSA-hr7j-63v7-vj7g: Pterodactyl Panel's SFTP sessions remain active after user account deletion or password change

Pterodactyl Panel has a security flaw where SFTP sessions (file transfer connections) stay active even after a user account is deleted or their password is changed, allowing continued access to server files with revoked credentials. This prevents administrators from immediately stopping access when they suspect a security breach, potentially allowing unauthorized people to read, modify, or delete files.
