{"id":"CVE-2026-61609","summary":"Pterodactyl's shared global rate-limit key on login and 2FA checkpoint enables unauthenticated panel-wide authentication lockout (DoS)","details":"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 -\u003eby(), 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.","aliases":["GHSA-xvc3-826v-xf47"],"modified":"2026-08-04T11:51:16.005793195Z","published":"2026-07-28T15:45:57.570Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61609.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-770"]},"references":[{"type":"WEB","url":"https://github.com/pterodactyl/panel/releases/tag/v1.13.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61609.json"},{"type":"ADVISORY","url":"https://github.com/pterodactyl/panel/security/advisories/GHSA-xvc3-826v-xf47"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61609"},{"type":"FIX","url":"https://github.com/pterodactyl/panel/commit/98079a01660a61980fe62a72b2c1d48f99c35a5e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pterodactyl/panel","events":[{"introduced":"dfa329ddf242908b60e22e3340ea36359eab1ef4"},{"fixed":"4de50090141f549967fa715ef42aaaee2b4fc983"}],"database_specific":{"extracted_events":[{"introduced":"1.7.0"},{"fixed":"1.13.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.12.4","v1.12.3","v1.12.2","v1.12.1","v1.12.0","v1.11.7","v1.11.6","v1.11.5","v1.11.4","v1.11.3","v1.11.2","v1.11.1","v1.11.0","v1.11.0-rc.2","v1.11.0-rc.1","v1.10.4","v1.10.3","v1.10.2","v1.10.1","v1.10.0","v1.9.2","v1.9.1","v1.9.0","v1.8.1","v1.8.0","v1.7.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61609.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
