CVE-2026-69102

MaxKey contains an unauthorized access vulnerability due to a hard-coded JWT signing secret in application-maxkey.properties that allows unauthenticated attackers to forge valid JWT tokens and authenticate as any user by exploiting the password-skipped login endpoint. Attackers can craft a JWT token signed with the publicly known default secret, submit it to the /sign/login/jwt/trust endpoint, and obtain a fully authenticated admin session with access to SSO application configuration and downstream application secrets.

Summary		(es) MaxKey contiene una vulnerabilidad de acceso no autorizado debido a un secreto de firma JWT codificado de forma rígida en application-maxkey.properties que permite a atacantes no autenticados forjar tokens JWT válidos y autenticarse como cualquier usuario explotando el endpoint de inicio de sesión sin contraseña. Los atacantes pueden crear un token JWT firmado con el secreto predeterminado conocido públicamente, enviarlo al endpoint /sign/login/jwt/trust, y obtener una sesión de administrador completamente autenticada con acceso a la configuración de la aplicación SSO y a los secretos de las aplicaciones descendentes.
