Background: every time dashcaddy-api restarts, the first POST from a
dashboard browser tab hits the missing-CSRF-cookie branch. The
status/js/globals.js secureFetch() wrapper catches the 403 and
auto-retries with a fresh token, so the WARN line is misleading noise.
Live evidence (DNS2, 2026-08-18 10:35:32Z container restart):
[CSRF] Missing CSRF cookie: POST /api/v1/backups/schedule from 100.121.150.22
[CSRF] Missing CSRF cookie: POST /api/v1/backups/schedule from 100.121.150.22
[CSRF] Missing CSRF cookie: POST /api/v1/backups/schedule from 172.17.0.1
Fix: if X-CSRF-Token header is ALSO present, tag the log line [CSRF-debug]
(operator can grep it out as expected noise — the secureFetch retry will
self-heal). A request with NEITHER cookie NOR header (curl probe, exploit
scanner, broken client) keeps the [CSRF] tag.
Threat model: forging a header without the cookie just produces a
different 403 (Invalid CSRF token) — the timingSafeEqual check on lines
248-260 of csrf-protection.js is unchanged. This is a log-only fix.
Tests: 4 new in __tests__/csrf-protection.test.js under
'DC-058: browser-auto-retry vs real-probe log tagging'. Full suite
1982/1982 green on DNS2 worktree.
GLM-5.3 judge (60s, 2 tool calls, sha 084672c parent 2f76b83):
GRADE=A — log tag branched only on headerToken presence with identical
403 body, headerToken read for tag-detection only (still validated via
timingSafeEqual at lines 248-260), 33 csrf tests + 33 regression tests
all pass. SHIP.
Pluggable AuthProvider framework for any future auth method (OIDC, SAML,
passkeys) to plug in without touching the auth path again. Two
implementations ship:
* TOTP — refactored from routes/auth/totp.js into src/auth/providers/totp.js
as one AuthProvider impl. Legacy /api/v1/totp/* routes stay mounted for
back-compat; new /api/v1/auth/login/totp/* routes use the new shape.
* EmailMagicLink — src/auth/providers/email.js. Initiate issues a 32-byte
base64url token, stores its SHA-256 hash in data/email-tokens.json
(atomic lockfile-based mutation, automatic TTL cleanup), and delivers via
nodemailer if providers.email.{host,port,username,password} is set OR
falls back to log.info('auth', 'email magic link issued', ...) for dev.
Verify accepts the token, marks it used, creates the same DashCaddy
session cookie that TOTP uses (single global cookie model).
createAuthProviderRegistry() composes both implementations and exposes
them via /api/v1/auth/login/{methods, :provider/initiate, :provider/verify,
recovery-info} and /api/v1/auth/disable/:provider. PUBLIC_ROUTES + CSRF
exemptions updated to use :provider placeholder (parameterized for future
providers).
Test fix: src/utilities/middleware.js PUBLIC_ROUTES and csrf-protection.js
both switched to the :provider form because the prior literal 'totp'
wouldn't match the parameterized mount path Express 4.22 produces.
Test fix: __tests__/public-routes-drift.test.js extractMountPath() was
broken for Express 4.22's new ^/path/?(?=/|$) source format (no \?\?
terminator in the literal-mount case). Rewrote the parser to normalize
escaped slashes + trailing lookaheads instead of relying on regex
matching against the raw source.
New: __tests__/auth-provider-registry.test.js — 9 tests covering registry
composition, getProvider round-trip, listEnabled no-secrets-leak guarantee,
enabled-flag respect, listAll vs listEnabled distinction, email provider
dev-console fallback (token written to JSON store + log.info with
deliveredVia: 'dev-console' + response masked), verify rejects unknown
tokens via AuthenticationError.
Tests: 1241/1241 passing across 46 suites (was 1232; +9 new).
DNS2 deploy: this commit + bump VERSION to 1.16.0 + publish tarball to
get.dashcaddy.net + docker build + bash start.sh. The image-layer migration
from DC-050 also runs on first container recreate post-merge.
Fresh users copy-pasting healthcheck blocks from k8s/Docker docs need
the standard short aliases. Without /healthz and /readyz they get
connection refused. This commit:
1. Adds /healthz + /readyz as root-level aliases for /health/live +
/health/ready in src/app.js. Handler bodies DRYed into named
functions (livenessHandler, readinessHandler) so a probe semantics
change updates all five paths at once.
2. Removes the dead /api/v1/health*, /api/v1/health/live, /api/v1/health/ready
registrations from PUBLIC_ROUTES and CSRF exclusion list — those
routes were never actually mounted on the apiRouter (only root
paths existed). Anyone probing /api/v1/health now gets a clean 404
instead of being routed through to a duplicate root handler.
3. Adds bypass for the 5 probe paths in three places where it matters:
- PUBLIC_ROUTES (no auth)
- csrf-protection.js excludedPaths (no CSRF check)
- middleware.js request-logging exclusion (k8s polling every 10s
doesn't flood the audit log)
- middleware.js Tailscale auth bypass (probes don't carry Tailscale
identity headers)
4. Adds __tests__/health-probe-aliases.test.js (19 tests):
- Alias equivalence (/healthz == /health/live, /readyz == /health/ready)
- Back-compat (/health == /health/live)
- Path consolidation (all 3 /api/v1/health* return 404)
- Source-of-truth PUBLIC_ROUTES allowlist sync check
- Source-of-truth src/app.js mount list sync check (catches drift
between handler mount and middleware allowlist)
5. Documents probes in README (copy-paste docker-compose.yml +
Kubernetes blocks) and user-guide (Health Probes section + System
API table updated).
Post-fix: 941/941 tests pass (+19 new). Zero new ESLint warnings
introduced. The pre-existing warnings/errors in src/app.js line 906
('os' is not defined) and the empty blocks in logging.test.js are
not regressions from this commit.
After the DC-005 module reorganization (41 files moved into src/ subdirs),
138 test suites failed because the refactor script's path-rewrite logic
missed three categories:
1. Files inside src/ doing 'require("./src/...")' — should be 'require("../...")'
2. Files in src/X/Y/ doing 'require("../../../src/...")' — should be 'require("../../...")'
3. Test files in __tests__/ with leftover 'require("../../../src/...")' paths
Root cause: the original refactor script ran before all files were moved,
so it computed relative paths against stale filesystem state.
Result:
- 30/30 test suites pass
- 879/879 tests pass (was: 18/30 suites, 614/687 tests)
Also fixed:
- routes/apps/restore.js: wrong responses import path
- routes/*/*.js: '../../src/utilities/X' → '../src/utilities/X' (depth 2 routes)
