CVE-2026-61609 Details
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.
A denial-of-service vulnerability has been identified in Pterodactyl Panel versions 1.7.0 prior to 1.13.0. The issue arises from the authentication rate limiter, which applies a single global bucket to login and two-factor authentication checkpoint endpoints. This global bucket is not keyed by IP or account, allowing an unauthenticated attacker to send approximately ten requests per minute from a single IP. The attack can be directed most effectively at the checkpoint endpoint, which lacks reCAPTCHA, exhausting the shared counter and causing HTTP 429 errors for all users attempting to log in or complete two-factor authentication. This panel-wide authentication denial-of-service also locks out administrators.
Users can upgrade to Pterodactyl Panel version 1.13.0 or later, where this vulnerability has been patched.
