Shankar	5c8d37e0f0	fix(bundle-5): Operational Liveness + Bootstrap — 4 audit findings closed ... Closes Audit-2026-04-25 H-006 (High), H-007 (High), M-011 (Medium), L-006 (Low — verified-already-closed via C-1 master closure in v2.0.54). Hardens the orchestrator-facing surface — k8s probes, agent enrollment, shutdown audit drain, scheduler config plumbing. What changed - internal/api/handler/health.go — split contract: * /health stays shallow 200 (k8s liveness — process alive) * /ready accepts *sql.DB; runs db.PingContext(2s); 503 on failure * Nil DB path returns 200 + db=not_configured (test fixtures) - internal/api/handler/agent_bootstrap.go (NEW) — verifyBootstrapToken: * empty expected = warn-mode pass-through * non-empty = `Authorization: Bearer <token>` required * crypto/subtle.ConstantTimeCompare; length-mismatch path runs dummy compare to keep timing uniform * ErrBootstrapTokenInvalid sentinel - internal/api/handler/agents.go — RegisterAgent calls verifyBootstrapToken BEFORE body parse so unauth probes don't even allocate a JSON decoder - internal/config/config.go — two new env vars: * CERTCTL_AGENT_BOOTSTRAP_TOKEN (Auth.AgentBootstrapToken) * CERTCTL_AUDIT_FLUSH_TIMEOUT_SECONDS (Server.AuditFlushTimeoutSeconds) - cmd/server/main.go — 3 changes: * pass *sql.DB into NewHealthHandler (H-006) * pass cfg.Auth.AgentBootstrapToken into NewAgentHandler (H-007) * configurable shutdown audit-flush timeout (M-011) * one-shot startup WARN when bootstrap token unset (deprecation) - new tests: agent_bootstrap_test.go (full deny/accept/warn-mode coverage, constant-time compare path, length-mismatch); health_test.go extended with /ready DB-probe failure (503), nil-DB pass-through, /health-shallow L-006 verified - cmd/server/main.go:557 already calls sched.SetShortLivedExpiryCheckInterval(cfg.Scheduler.ShortLivedExpiryCheckInterval) per the C-1 master closure in v2.0.54. Bundle 5 confirms; no code change. Threat model: TB-1 (operator/orchestrator), TB-2 (Agent↔Server). - CWE-754 (Improper Check for Unusual or Exceptional Conditions) for H-006 - CWE-306 + CWE-288 (Missing Authentication for Critical Function) for H-007 Verification - go vet ./... → clean - go build ./... → clean - go test -short -count=1 ./... → all packages pass - targeted Bundle-5 regressions → all pass - npx tsc --noEmit (web) → clean - npx vitest run (web) → in-flight (sandbox 45s ceiling exceeded; no failure markers in dot stream; no frontend changes in this bundle so no regression risk) - python3 yaml.safe_load(api/openapi.yaml) → 89 paths Backward compatibility - Bootstrap token defaults to empty (warn-mode) — existing demo deployments unaffected. Server logs deprecation WARN; v2.2.0 will require it. - Audit flush timeout default 30s preserves prior behaviour. - Helm chart already routes readiness probe to /ready (no chart change needed); now /ready actually probes the DB. Bundle 5 of the 2026-04-25 comprehensive audit.	2026-04-25 23:54:18 +00:00
Shankar	54a41603de	fix(security,config): remove unimplemented JWT auth-type, close silent downgrade (G-1) ... The pre-G-1 config validator accepted CERTCTL_AUTH_TYPE=jwt and the startup log faithfully echoed 'authentication enabled type=jwt'. Reasonable people read that and concluded JWT auth was on. It wasn't. The auth-middleware wiring at cmd/server/main.go unconditionally routed every request through the api-key bearer middleware regardless of cfg.Auth.Type. So CERTCTL_AUTH_TYPE=jwt quietly compared the incoming 'Authorization: Bearer <token>' against whatever string the operator put in CERTCTL_AUTH_SECRET — real JWT clients got 401, and operators who treated CERTCTL_AUTH_SECRET as a *signing* secret (because they thought they were configuring JWT) had effectively handed an attacker an api-key. A security finding masquerading as a config option. We chose the audit-recommended structural fix: remove the option, fail fast at startup, and add the gateway-fronting pattern as the documented forward path. Implementing JWT middleware would have meant jwks vs static-secret rotation, claim mapping, expiry enforcement, audience and issuer validation, key rollover semantics, and regression coverage at the same depth as the existing api-key path — a feature, not a fix. Operators who genuinely need JWT/OIDC front certctl with an authenticating gateway (oauth2-proxy / Envoy ext_authz / Traefik ForwardAuth / Pomerium / Authelia) and run the upstream certctl with CERTCTL_AUTH_TYPE=none. Same shape works on docker-compose and Helm. The change is comprehensive across 7 phases — every surface that mentioned 'jwt' as a certctl-auth-type is updated, plus structural backstops (typed enum, runtime guard, helm template validation, CI grep guard) so the lie can't reappear. Files changed: Phase 1 — production code (typed enum + jwt removal): - internal/config/config.go: AuthType typed alias + AuthTypeAPIKey / AuthTypeNone constants + ValidAuthTypes() helper. Validate() routes literal 'jwt' through a dedicated multi-line diagnostic naming the authenticating-gateway pattern, then cross-checks against ValidAuthTypes(). Secret-required branch simplified to api-key-only. Field comment on AuthConfig.Type rewritten to drop jwt and point at the gateway pattern. - internal/api/middleware/middleware.go: AuthConfig.Type field comment references the typed config.AuthType constants. - internal/api/handler/health.go: same treatment for HealthHandler.AuthType. - cmd/server/main.go: defense-in-depth runtime switch immediately after config.Load() — exits 1 on any unsupported auth-type that bypassed the validator. Auth-disabled startup log explicitly names the authenticating-gateway pattern. Phase 2 — tests (Red→Green, contract pinning): - internal/config/config_test.go: TestValidate_JWTAuth_RejectedDedicated (two table rows pinning the dedicated G-1 error fires regardless of whether Secret is set), TestValidAuthTypesDoesNotContainJWT (property guard against future re-introduction), TestValidAuthTypesIsExactly_APIKey_None (allowed-set contract), TestValidate_GenericInvalidAuthType (pins non-jwt invalid values still hit the generic invalid-auth-type error). Removed the prior TestValidate_JWTAuth_MissingSecret happy-path since its premise is inverted post-G-1. - internal/api/handler/health_test.go: removed TestAuthInfo_ReturnsAuthType_JWT (which baked the silent-downgrade lie into the regression suite). Pre-existing _APIKey test continues to cover the api-key happy path. Phase 3 — spec, docs, env templates: - api/openapi.yaml: auth_type enum dropped to [api-key, none] with inline comment naming the G-1 closure. - .env.example (root): CERTCTL_AUTH_TYPE comment block rewritten to drop jwt and point at the gateway pattern; secret-required conditional simplified to api-key-only. - docs/architecture.md: middleware-stack bullet rewritten to drop the JWT mention; new H3 'Authenticating-gateway pattern (JWT, OIDC, mTLS)' section explaining the design rationale and listing oauth2-proxy / Envoy ext_authz / Traefik ForwardAuth / Pomerium / Authelia / Caddy forward_auth / Apache mod_auth_openidc / nginx auth_request as the standard fronting options. - docs/upgrade-to-v2-jwt-removal.md (new ~125 lines): migration guide with preconditions, what-changes, both recovery paths, complete docker-compose oauth2-proxy walkthrough, Traefik ForwardAuth and Envoy ext_authz patterns, rollback posture. Phase 4 — Helm chart (template validation + docs): - deploy/helm/certctl/templates/_helpers.tpl: new certctl.validateAuthType helper mirroring the existing certctl.tls.required pattern. Fails template render on any server.auth.type outside {api-key, none} with a multi-line diagnostic. - deploy/helm/certctl/templates/server-deployment.yaml, server-configmap.yaml, server-secret.yaml: invoke the helper at the top of each template that depends on .Values.server.auth.type. - deploy/helm/certctl/values.yaml: auth: block comment expanded with the G-1 rationale and gateway-pattern cross-reference. - deploy/helm/CHART_SUMMARY.md: server.auth.type table row now surfaces the allowed set and points at the upgrade doc. - deploy/helm/certctl/README.md: new 'JWT / OIDC via authenticating gateway' section with a Kubernetes-flavored oauth2-proxy + certctl walkthrough. Phase 5 — release surface: - CHANGELOG.md: new [unreleased] top entry with Breaking / Removed / Added / Changed sections; explicit pointer at docs/upgrade-to-v2-jwt-removal.md from the Breaking subsection. Phase 6 — CI guardrail: - .github/workflows/ci.yml: new 'Forbidden auth-type literal regression guard (G-1)' step. Scoped patterns catch the actual regression shapes (map literal, slice literal, switch case, OpenAPI enum, env-file default, AuthType('jwt') cast). Comments and the dedicated rejection branch are intentionally exempt; connector-package JWT references (Google OAuth2 / step-ca) are exempt as out-of-scope external protocols. Verified locally: the guard passes on the actual tree and fires on all 4 synthetic regression patterns. Out of scope (explicitly untouched): - internal/connector/discovery/gcpsm/gcpsm.go — Google OAuth2 service- account JWT (external protocol). - internal/connector/issuer/googlecas/googlecas.go — same. - internal/connector/issuer/stepca/stepca.go — step-ca's provisioner one-time-token JWT for /sign API. - docs/test-env.md, docs/connectors.md, docs/features.md — describe external CAs' use of JWT, not certctl's auth shape. - Implementing actual JWT middleware. Feature, not a fix. Verification (all gates pass): - go build ./... — clean - go vet ./... — clean - go test -short ./... — every package green - go test -short -race ./internal/config/... ./internal/api/... — clean - govulncheck ./... — no vulnerabilities in our code - helm lint deploy/helm/certctl/ — clean - helm template with auth.type=api-key — renders OK - helm template with auth.type=none — renders OK - helm template with auth.type=jwt — fails with validateAuthType diagnostic (exit 1) - python3 yaml.safe_load on api/openapi.yaml — parses - CI guardrail mirror — clean on real tree, fires on all 4 synthetic regression patterns - Smoke test: 'CERTCTL_AUTH_TYPE=jwt ./certctl-server' exits non-zero with: 'Failed to load configuration: CERTCTL_AUTH_TYPE=jwt is no longer accepted (G-1 silent auth downgrade): no JWT middleware ships with certctl. To use JWT/OIDC, run an authenticating gateway (oauth2-proxy / Envoy ext_authz / Traefik ForwardAuth / Pomerium) in front of certctl and set CERTCTL_AUTH_TYPE=none on the upstream. See docs/architecture.md "Authenticating-gateway pattern" and docs/upgrade-to-v2-jwt-removal.md for the migration walkthrough' config pkg coverage: ValidAuthTypes 100%, Validate 94.7%, total 75.5%.

Shankar Reddy	45361477ed	Unify API auth + RFC-compliant CRL/OCSP (M-002 + M-003 + M-006, auto-closes M-001) ... Closes the remaining P1 gaps from coverage-gap-audit.md (M-001/M-002/M-003/M-006) on top of the C-001/C-002 ownership + agent-FK contract fixes landed in 5c01c7f. The work lands as a single commit spanning server, docs, tests, and the React client. M-002 — Named API keys with per-key actor propagation * Migration 000014 adds the 'api_keys' table (id, name, hash, principal, role, created_at, last_used_at, disabled_at) so every credential carries an identifiable principal instead of the opaque 'anonymous'/'api-key' sentinel. * Auth middleware now rotates through configured keys, performs constant-time hash comparison, stamps 'last_used_at', and emits an actor struct via contextWithActor(). The audit middleware, bulk-revocation handler, approval handlers, and MCP tool layer now read the principal off the context and persist it on every audit_events row. * Regression coverage: - internal/api/middleware/audit_test.go — actor propagation, principal redaction for disabled keys, anonymous fallback for unauthenticated endpoints. - internal/api/handler/bulk_revocation_handler_test.go, job_handler_test.go — principal-on-audit assertions. M-003 — Authorization gates (Phase B) * Approval handler rejects self-approval / self-rejection with 403 when the actor principal equals the job's requested_by field. * Bulk revocation is gated behind the 'admin' role; operators and viewers receive 403. * Regression coverage: - internal/service/job_test.go — TestApproveJob_NotSelf, TestRejectJob_NotSelf. - internal/api/handler/bulk_revocation_handler_test.go — TestBulkRevoke_RequiresAdmin, TestBulkRevoke_AdminSucceeds. M-006 — RFC-compliant CRL/OCSP on the unauthenticated .well-known mux * Per RFC 8615, relying parties cannot reasonably be asked to authenticate against the issuing certctl instance to retrieve revocation material. CRL and OCSP move off the authenticated '/api/v1/crl*' and '/api/v1/ocsp/*' paths onto: GET /.well-known/pki/crl/{issuer_id} Content-Type: application/pkix-crl (RFC 5280 §5) GET /.well-known/pki/ocsp/{issuer_id}/{serial} Content-Type: application/ocsp-response (RFC 6960) * Non-standard JSON CRL shape is removed; only DER is served. * Short-lived certificate exemption (profile TTL < 1h → skip CRL/OCSP) is preserved; the response simply omits the serial. * Routes are registered on the unauthenticated 'finalHandler' mux in cmd/server/main.go alongside EST ('/.well-known/est/*') and SCEP ('/scep'). Legacy authenticated paths return 404. * Regression coverage: - internal/api/handler/certificate_handler_test.go — content type, DER parseability, 404 for unknown issuer. - internal/api/handler/adversarial_path_test.go — unauthenticated access asserted for CRL, OCSP, EST, SCEP. - internal/api/router/router_test.go — route-table assertion that '.well-known/pki/*', '.well-known/est/*', and '/scep' are mounted on the unauthenticated branch. M-001 — Auto-closed by M-002 EST and SCEP were already registered on the unauthenticated 'finalHandler' mux; the router comment at internal/api/router/router.go:247 now matches reality. The adversarial-path tests above lock the behavior in. Verification (all gates green): * go vet ./... — clean * go build ./... — ok * go test -short ./... (55+ packages) — all pass * web/ : npm test (225 Vitest tests) — all pass * web/ : npx tsc --noEmit — clean * grep sweep for '/api/v1/(crl|ocsp)' — 13 surviving hits, all intentional M-006 tombstone/relocation comments. Documentation: * coverage-gap-audit.md — status flips M-001/M-002/M-003/M-006 → Fixed, with per-finding resolution paragraphs citing regression test IDs. (Audit file lives outside this repo; see cowork root.) * CLAUDE.md Project Status line updated with the auth-unification closure note. * docs/features.md, docs/architecture.md, docs/quickstart.md, docs/concepts.md, docs/connectors.md, docs/test-env.md, docs/testing-guide.md, docs/compliance-*.md, docs/demo-advanced.md — refreshed for the new '.well-known/pki/*' namespace and named API keys. * api/openapi.yaml — documents the new unauthenticated endpoints and removes the legacy '/api/v1/crl*' + '/api/v1/ocsp/*' paths. .gitignore: adds '/.gocache/' and '/.gomodcache/' for the session- scoped Go caches so they never enter the tree.	2026-04-18 18:17:41 +00:00
