CVE-2026-69102
CriticalCVSS 9.8Summary
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.
Risk Assessment
The risk includes full compromise of administrator accounts and access to sensitive SSO configurations and secrets, potentially leading to severe security breaches.
Recommendation
It is recommended to immediately change the default JWT secret to a unique, strong secret and update MaxKey to a patched version.
