Summary
A vulnerability in Pterodactyl causes a global login rate limit affecting all users. The limit is global, not per IP, allowing an attacker to block login for everyone by sending about 10 requests per minute.
Risk Assessment
An attacker can cause a complete authentication denial of service in the panel, preventing even administrators from logging in.
Recommendation
Update Pterodactyl to version 1.13.0 or later.
Other vulnerabilities in Pterodactyl
See all- CVE-2026-54593High
A vulnerability in Pterodactyl allows an authenticated subuser to write arbitrary files to the server without the required permissions. A JWT token issued for other operations (e.g., WebSocket) can be reused for file uploads.
- CVE-2026-35202Low
Vulnerability in Pterodactyl prior to version 1.12.3. A logic flaw in the Client API allows users to bypass database allocation limits due to a broken locking mechanism.
Original NVD description (English source)
Pterodactyl is a free, open-source game server management panel. From 1.7.0 until 1.13.0, the authentication rate limiter defined in RouteServiceProvider::configureRateLimiting() applied a single global bucket to the login and two-factor checkpoint endpoints instead of keying by IP or account: the fall-through Limit::perMinute(10) covering POST /auth/login and POST /auth/login/checkpoint omitted ->by(), so Laravel derived a constant cache key (md5('authentication')) shared by every request. An unauthenticated attacker sending roughly ten requests per minute from a single IP, most cheaply against the checkpoint endpoint (which has no reCAPTCHA), exhausts the shared counter and causes HTTP 429 for every user attempting to log in or complete two-factor authentication, a panel-wide authentication denial of service that also locks out administrators. This issue is fixed in version 1.13.0.
