CVE-2026-61609

Pterodactyl's shared global rate-limit key on login and 2FA checkpoint enables unauthenticated panel-wide authentication lockout (DoS)

Published Jul 28, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
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.
