Vulnerability Title
Pterodactyl has a database resource limit bypass via race condition in Client API
Source: CVE Program / CVE List V5
Vulnerability Description
Pterodactyl is a free, open-source game server management panel. Prior to version 1.12.3, the Pterodactyl Client API has a logic flaw that lets users bypass their assigned limits for database allocations. This happens because the database locking mechanism used in the controllers is totally broken and doesn't actually lock anything. Version 1.12.3 patches the issue.
