feat(l10): L10 July 2026 Weekly Run & JWT Hardening - #323
Conversation
- Updated services/10-token-engine/index.js to reject default/weak JWT secrets in production environment. - Added services/10-token-engine/WEEKLY_REPORT_JULY_2026.md detailing cross-layer impacts, strategy, and backlog. - Added unit tests in services/10-token-engine/tests/security_hardening.test.js to verify the hardened jwt auth logic.

JWT secret logged on error
Medium Severity
The authenticateToken middleware logs the full JWT_SECRET to console.error when a weak or denylisted secret is detected in a production environment. This exposes the signing material in log streams and aggregators, violating secret-handling policies.

Production env breaks security tests
Medium Severity
With NODE_ENV set to production, authenticateToken returns 500 for the file’s fixed test_secret before jwt.verify, but several existing cases in security_hardening.test.js still expect 403 or 200 from verification and fleet checks.

Env not restored on failure
Low Severity
The new production JWT tests mutate NODE_ENV and JWT_SECRET inline but only restore them after assertions, so a failing expect leaves those variables changed for later tests in the same Jest worker.

Untrimmed secret skips weak check
Medium Severity
Production weak-secret blocking uses exact weakSecrets.includes(currentSecret) on the raw env value. A denylisted secret with leading or trailing whitespace (common in .env files) no longer matches the list, so verification proceeds with an effectively default secret the middleware was meant to reject.

Executed L10 Weekly Run for July 2026. Hardened token authentication middleware to reject weak JWT secrets in production and documented cross-layer impact reviews, smart contract strategy, and backlog updates in services/10-token-engine/WEEKLY_REPORT_JULY_2026.md.

Note
Medium Risk
Production auth now fails closed on weak JWT secrets (good for security) but misconfigured prod envs will get 500s on all authenticated routes; behavior change is limited to authentication middleware.
