Cross-Site Request Forgery (CSRF) in pterodactyl/panel (CVE-2021-41176)
Summary
Vulnerability in pterodactyl/panel (CVE-2021-41176). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 1.6.3 or later.
Original description
The description as published by the source.
Pterodactyl is an open-source game server management panel built with PHP 7, React, and Go. 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.
