CVE-2025-69971
HIGH8.1EPSS 4.5%FUXA has a hardcoded fallback JWT signing secret
Published: 2/3/2026Modified: 5/11/2026
Description
FUXA used a static fallback JWT signing secret (`frangoteam751`) when no `secretCode` was configured. If authentication was enabled without explicitly setting a custom secret, an attacker who knew the default value could forge valid JWT tokens and bypass authentication. This issue has been addressed in version 1.3.0 by removing the static fallback and generating a secure random secret when no `secretCode` is provided.
