Roadmap item: P1 - Security hardening

auth.py ships a fallback secret sparc-secret-key-change-in-production that will be used if JWT_SECRET is unset. This is a critical security risk in production.

What to do

  • In auth.py (or application startup), detect if the running JWT_SECRET value equals the default fallback string
  • If ENVIRONMENT (or equivalent env var) is not development and the secret is the default, raise a RuntimeError or call sys.exit(1) with a clear error message
  • Add a unit test that asserts startup fails when default secret is used in a non-dev environment

Acceptance criteria

  • Application refuses to start in production with the default JWT secret
  • A clear error message is logged indicating how to fix (set JWT_SECRET)
  • Dev/test environments can still run without setting JWT_SECRET
  • Test covers the startup guard logic

Triage: Already Resolved

This issue has been implemented in the current codebase. The check_jwt_secret() function exists in SPARC/auth.py (line 23) and is called during API startup in SPARC/api.py (line 181). It correctly refuses to start when JWT_SECRET equals the default value and APP_ENV is not development.

The .env.example also documents this behavior. Tests exist in tests/test_security.py.

Closing as resolved.
