Follow-up to the /terminal authorization fix: a full-codebase security
review surfaced several more issues, fixed here. All changes are designed
to roll out with no interruption to existing deployments — no forced
migration, no manual re-key, no boot failure.
Self-healing secret management (utils/secrets.ts):
- JWT_SECRET / ENCRYPTION_KEY auto-generate to strong values on first boot
and persist to the app_data volume (0600, outside the DB) when not set
to a strong value in the environment. Replaces the prior behavior of
running on the public repo defaults.
- decrypt() tries the current key plus every legacy/default key, so
existing device credentials keep decrypting after a key change; a
startup sweep re-encrypts stale rows forward (db/reencryptCredentials.ts).
- verifyToken() accepts the current signing secret plus prior *strong*
secrets (never the public defaults), so rotation doesn't invalidate live
sessions; sessions signed with a default secret require one re-login.
- Dockerfile pre-creates /app/data as the app user so the non-root
process can persist to a fresh named volume; app_data volume added to
both compose files; compose secret defaults changed to empty (auto-gen).
Authorization / input:
- Default Socket.IO namespace now requires a valid JWT (was unauthenticated
and broadcasting fleet-activity events); frontend sends the token and
drops the shared socket on logout.
- Webhook delivery blocks SSRF to loopback/private/link-local/CGNAT ranges
and pins the request to the validated IP (WebhookService.ts).
- Rate limit added to /auth/totp/verify; global mutation backstop on /api.
- Password policy (>=10 chars, letter+digit) enforced on set/change/create.
- system.ts used verifyToken as middleware (always 500); now requireAuth.
Hardening:
- CSP + HSTS/nosniff/frame-deny headers in nginx, scoped to allow the
OpenStreetMap tile/geocoding hosts the maps use.
Docs/tests:
- README secret section rewritten for the self-healing model.
- New unit tests for secret resolution, persistence, rotation, and
legacy-key decryption (97 tests pass).
