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.
Recommendation
Update the @frangoteam/fuxa package to the latest compatible version. Followings are version details:
- Affected version(s): <= 1.2.11
