Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

github.com/dhax/go-base versions before 0.0.0-20260517152733-cc82b9740fa6 default the JWT signing secret to the public value "random". Anyone who knows this can forge tokens for any user, including admins, and bypass authentication. Upgrade to 0.0.0-20260517152733-cc82b9740fa6 and set your own strong JWT secret.
