CVE-2026-35202 PUBLISHED

Pterodactyl has a database resource limit bypass via race condition in Client API

Assigner: GitHub_M
Reserved: 01.04.2026 Published: 02.06.2026 Updated: 03.06.2026

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.
