CVE ID :CVE-2026-34456 Published : April 1, 2026, 8:16 p.m. | 39 minutes ago Description :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.
