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.
- CVE-2025-69197Medium
Pterodactyl is a free, open-source game server management panel. Versions 1.11.11 and below allow TOTP to be used multiple times during its validity window. After sign-in, the token is not sufficiently marked as used, allowing an attacker who intercepted the token (e.g., during a screen share) to reuse it within the 60-second validity window along with known credentials. This is fixed in version 1.12.0.
- CVE-2025-68954Medium
Pterodactyl is a free, open-source game server management panel. Versions 1.11.11 and below do not revoke active SFTP connections when a user is removed from a server instance or has their permissions changes with respect to file access over SFTP. This allows a user that was already connected to SFTP to remain connected and access files even after their permissions are revoked. A user must have been connected to SFTP at the time of their permissions being revoked in order for this vulnerability to be exploited. This issue is fixed in version 1.12.0.
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.
