CVE-2026-71206

Shiori's CheckToken function (internal/domains/auth.go) validates only the JWT's HMAC signature and returns the embedded claims.Account object unmodified, never re-fetching the account from the database. No session store or token-revocation mechanism exists in the codebase.

Summary		(es) La función CheckToken de Shiori (internal/domains/auth.go) valida únicamente la firma HMAC del JWT y devuelve el objeto claims.Account incrustado sin modificar, sin volver a obtener la cuenta de la base de datos. No existe un almacén de sesiones ni un mecanismo de revocación de tokens en el código base. Eliminar una cuenta o degradarla de propietario a un rol regular no tiene efecto en los tokens ya emitidos a esa cuenta - un token de propietario eliminado o degradado continúa autenticándose con sus privilegios originales de nivel de propietario hasta su caducidad natural, que puede ser de hasta 30 días con ’recordarme’ habilitado.
