CVE-2026-69102Public exploitNetwork attack vector

Unauthenticated account impersonation via hard-coded JWT secret

Published Aug 11, 2026 · Updated Aug 11, 2026

Authentication bypass in Dromara MaxKey 4.1.11 and earlier allows remote attackers to impersonate any enabled user through a forged JWT. The /sign/login/jwt/trust handler verifies only an HS512 signature made with the fixed maxkey.auth.jwt.secret, then passes the token subject to a password-skipped login. Exposure requires JWT login to remain enabled and the shipped secret to remain unchanged; successful impersonation grants an administrator session that can read or modify SSO application configuration and downstream secrets.
