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
