CVE-2026-35202: CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition in pterodactyl panel
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.
AI Analysis
Technical Summary
CVE-2026-35202 is a TOCTOU race condition vulnerability in the Pterodactyl panel's Client API before version 1.12.3. The flaw arises because the database locking mechanism in the controllers does not effectively lock resources, allowing users to bypass their assigned database allocation limits. This logic error can lead to inconsistent enforcement of resource limits. The vulnerability is fixed in version 1.12.3.
Potential Impact
Users with limited privileges can bypass database allocation limits due to ineffective locking, potentially leading to resource over-allocation. The CVSS score of 2.3 and low severity rating indicate that the impact is limited and exploitation requires some privileges and conditions.
Mitigation Recommendations
Upgrade to Pterodactyl panel version 1.12.3 or later, where the issue is patched. No other mitigation is indicated or necessary.
