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 time-of-check time-of-use (TOCTOU) race condition vulnerability in the Pterodactyl game server management panel. The issue arises from a flawed database locking mechanism in the Client API controllers, which fails to enforce assigned limits on database allocations. This logic flaw allows users to bypass these limits. The vulnerability affects all versions prior to 1.12.3, which includes the fix. The CVSS 4.0 base score is 2.3, indicating low severity.
Potential Impact
Users can bypass assigned database allocation limits due to the ineffective locking mechanism, potentially leading to resource misallocation or abuse within the Pterodactyl panel environment. There are no reports of known exploits in the wild, and the impact is limited by the low severity rating.
Mitigation Recommendations
Upgrade to Pterodactyl panel version 1.12.3 or later, where the database locking mechanism flaw has been fixed. Since the vendor has released a patched version, applying this official fix is the recommended remediation. Patch status is confirmed by the version information in the advisory.
