CVE-2026-69102

critical · 9.3

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.
