CVE-2026-34456

critical · 9.1

Reviactyl is an open-source game server management panel built using Laravel, React, FilamentPHP, Vite, and Go. From version 26.2.0-beta.1 to before version 26.2.0-beta.5, a vulnerability in the OAuth authentication flow allowed automatic linking of social accounts based solely on matching email addresses. An attacker could create or control a social account (e.g., Google, GitHub, Discord) using a victim’s email address and gain full access to the victim's account without knowing their password. This results in a full account takeover with no prior authentication required. This issue has been patched in version 26.2.0-beta.5.
