In affected versions of Pterodactyl a malicious user can trigger a user logout if a signed in user visits a malicious website that makes a request to the Panel's sign-out endpoint. This requires a targeted attack against a specific Panel instance, and serves only to sign a user out. **No user details are leaked, nor is any user data affected, this is simply an annoyance at worst.** This is fixed in version 1.6.3.","published":"2021-10-25T17:15:09.380Z","modified":"2026-08-07T19:48:41.410316Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"pterodactyl/panel","fixedVersion":"1.6.3"}],"fix":{"url":"https://github.com/pterodactyl/panel/commit/45999ba4ee1b2dcb12b4a2fa2cedfb6b5d66fac2","label":"pterodactyl/panel@45999ba"},"references":[{"type":"ADVISORY","url":"https://github.com/pterodactyl/panel/releases/tag/v1.6.3"},{"type":"ADVISORY","url":"https://github.com/pterodactyl/panel/security/advisories/GHSA-m49f-hcxp-6hm6"},{"type":"FIX","url":"https://github.com/pterodactyl/panel/commit/45999ba4ee1b2dcb12b4a2fa2cedfb6b5d66fac2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T19:48:41.410316Z"}}
