Unreleased

Security

• OIDC provider "Test connection" panel (Audit 2026-05-11 Fix 09 — MED-5 GUI half). MED-5's backend dry-run endpoint (POST /api/v1/auth/oidc/test, gated auth.oidc.create) shipped on dev/auth-bundle-2 but had no GUI caller — the authOIDCTestProvider function in web/src/api/client.ts was dead code. Operators had to complete the create form blind, save, then click "Refresh" to discover whether the issuer URL worked; failures left a broken provider row in the database that had to be deleted before retrying. New shared component web/src/pages/auth/OIDCTestConnectionPanel.tsx calls the backend against the live form state and renders a four-row status panel inline: Discovery fetched, JWKS reachable, supported algs (warns when the IdP advertises none), and RFC 9207 iss-parameter advertisement (informational · glyph, not ✗, because the spec is SHOULD). Backend per-leg errors[] flow into an inline bullet list. The panel is mounted in the OIDCProvidersPage create modal AND the OIDCProviderDetailPage edit form — the edit-form half is load-bearing for verifying IdP rotations (Keycloak realm rename, Okta tenant move) without committing first. Run button is disabled until the issuer URL is non-empty (whitespace-trimmed); the component is read-only — safe to run repeatedly. 8 Vitest tests pin the glyph-vs-glyph contract (✓/✗/⚠/·), the button-disabled-without-issuer shape, and the test-id-suffix collision-prevention when the panel is mounted twice on the same page.

• Scope-aware actor-role revoke (Audit 2026-05-11 A-4). HIGH-10 made it possible to grant the same role to the same actor at multiple scopes (e.g. r-operator on profile=p-acme AND profile=p-globex) via the unique constraint extension on actor_roles, but ActorRoleRepository.Revoke ignored (scope_type, scope_id) and unconditionally deleted every variant. Operators who wanted to drop one scoped grant had to nuke them all and re-grant the remainder — a race window where the actor's access was briefly different. The DELETE /v1/auth/keys/{id}/roles/{role_id} endpoint now accepts optional ?scope_type= / ?scope_id= query params that narrow the revoke to a single variant; no-match returns 404. The legacy "revoke every variant" semantic is preserved when the query params are absent, so existing CLI / GUI buttons keep working unchanged. The audit row's details payload records which mode fired so SOC / SIEM can distinguish wide cleanups from targeted demotions. MCP tool certctl_auth_revoke_role_from_key gains optional scope_type + scope_id input fields with matching semantics. Documented in docs/operator/rbac.md under "Revoke: legacy 'all variants' vs scope-selective."

Security (BREAKING — silent-elevation closure)

• HIGH-10 actor-role scope is now enforced (Audit 2026-05-11 A-1). Pre-fix, actor_roles.scope_type / scope_id (added in migration 000043 by the HIGH-10 closure) were persisted by Grant + accepted on the handler body + surfaced through the GUI/MCP — but the load-bearing EffectivePermissions SQL never read them. A profile-scoped grant silently elevated to global at authorization time. Canonical CRIT-5 lying-field shape, replicated. The post-fix authorization narrows correctly: every existing actor_roles row with scope_type != 'global' now takes effect.

  Operator advisory: if you used the HIGH-10 scope-bound role-grant API between commit 551812b and the v2.1.0 tag (the column was populated but ignored), the grants were silently global. After upgrading, audit SELECT actor_id, role_id, scope_type, scope_id FROM actor_roles WHERE scope_type != 'global' and confirm the narrowing reflects intent. If an actor was granted a scoped role but expected global behavior, re-grant with scope_type=global.

Security (BREAKING)

• Federated-user deactivation now actually blocks login (Audit 2026-05-11 A-2). The MED-11 closure shipped users.deactivated_at + DELETE /api/v1/auth/users/{id}
  • cascade-session-revoke, but the column was a "lying field" three legs over: the postgres user repository never SELECTed it (so User.DeactivatedAt always read nil), the Update SQL never wrote it (so the handler's mutation was a no-op), and the OIDC upsertUser path never checked it (so the next login under the same (provider, subject) tuple re-minted a session and re-elevated the user). The cascade-revoke remained correct for the current cookie only. Operator advisory: if you deactivated a federated user between the MED-11 closure (Bundle 2 merge dea5053) and the v2.1.0 release tag, verify the user cannot OIDC-log-in after upgrading — the column took no effect at login time before this fix. If needed, re-run the deactivation against the upgraded server. Closure: userColumns + scanUser now read deactivated_at via sql.NullTime; Create + Update write it explicitly; upsertUser returns the new ErrUserDeactivated sentinel before mutating fields (preserves last_login_at forensics on rejected logins); classifyOIDCFailure surfaces the rejection as audit category user_deactivated. Self-deactivate guard on DELETE /api/v1/auth/users/{id} returns HTTP 409 + audit row auth.user_deactivate_self_rejected (prevents an admin from one-way-door locking themselves out via the standard handler — break-glass remains the recovery path). New inverse endpoint POST /api/v1/auth/users/{id}/reactivate (gated auth.user.deactivate — reactivation is the inverse op, not a separate privilege) clears deactivated_at; emits audit row auth.user_reactivated. Sessions revoked at deactivation stay revoked across reactivation — the user must complete a fresh OIDC login. GUI: UsersPage.tsx now renders a Reactivate button on deactivated rows. CWE-862 (missing authorization at the user-state boundary). SOC 2 CC6.3 + ISO 27001 A.9.2.6 compliance-table-flipping fix.
• __Host- cookie prefix on all three auth cookies (Audit 2026-05-10 MED-14). The session cookie, CSRF cookie, and OIDC pre-login cookie are renamed from certctl_session / certctl_csrf / certctl_oidc_pending to __Host-certctl_session / __Host-certctl_csrf / __Host-certctl_oidc_pending to gain browser-enforced subdomain-takeover protection (a __Host-* cookie can only be set with Path=/ + Secure + no Domain attribute, and the browser rejects subdomain attempts to overwrite it). Active sessions invalidate on the rolling deploy that lands this change — operators must re-authenticate once after upgrading. The GUI's CSRF cookie reader was updated in lockstep. See docs/migration/oidc-enable.md for operator-facing detail.

Security

• OIDC allowed_email_domains now editable in the GUI (Audit 2026-05-11 A-3). The backend gate that rejects logins whose email domain is outside the configured allowlist landed in v2.1.0 (CRIT-5 closure, 2026-05-10), but the GUI never exposed the field — GUI-driven operators had to use the API directly to configure tenant isolation against multi-tenant IdPs (Auth0, Azure AD common endpoint, Google Workspace). The OIDCProvidersPage create modal and OIDCProviderDetailPage detail view now render a chip-style multi-input with client-side validation that mirrors the backend rules (no @, no whitespace, no wildcards, lowercase-only FQDNs). The read-only view renders an explicit "any (no gate configured)" sentinel when the list is empty so operators can tell "not configured" apart from "field is invisible." A "Clear all" button on the edit form is gated by a confirm dialog that warns about removing the tenant gate. Operator advisory: if you provisioned OIDC providers via the GUI between v2.1.0 and this fix, verify allowed_email_domains matches your tenant policy — the field was configurable only via API / MCP / direct SQL during that window. Per-IdP runbooks for multi-tenant IdPs in docs/operator/oidc-runbooks/ already documented the field; the GUI now matches.

• Approval payload preview (Audit 2026-05-11 A-5). The MED-10 closure claim ("PARTIAL: raw JSON preview; diff library deferred") was inaccurate — ApprovalsPage.tsx rendered no payload at all, so approvers were clicking Approve / Reject without seeing the change they were authorizing. That defeats the entire four-eyes primitive: an approver who can't see what they're approving is rubber-stamping. Each row now carries a Preview toggle that expands an inline panel dispatching by kind: profile_edit shows a field-level before/after diff (changed-only rows, red/green cells, (unset) sentinel for added/removed fields); cert_issuance shows a definition list of CN / SANs / profile / key algo / must-staple / validity (catches the wildcard-against-corp-internal-profile attack at review time); unknown kinds render a generic JSON preview for forward-compat with future approval kinds. The base64-encoded JSON payload is decoded via the new decodePayload helper; malformed inputs render an explicit decode-error fallback — silent failure on the payload preview is what produced this bug in the first place.

• Strict pre-login UA/IP binding (Audit 2026-05-11 A-6). The MED-16 closure left a request-side empty-header bypass: when the pre-login row carried a User-Agent or client-IP binding but the /auth/oidc/callback request omitted the corresponding value, the binding check was silently skipped. curl doesn't send User-Agent by default; many programmatic clients omit it. An attacker who acquired a pre-login cookie could replay it without the bound header and bypass the RFC 9700 §4.7.1 defense. The check is now strict-when-stored — an empty request-side value with a non-empty stored binding rejects with HTTP 400 and the new audit failure categories prelogin_ua_missing / prelogin_ip_missing (distinct from the existing *_mismatch categories so SIEM rules can alert specifically on bypass attempts). Operator advisory: environments where the User-Agent is stripped in transit (some debug proxies, a handful of CDN configurations) must set CERTCTL_OIDC_PRELOGIN_REQUIRE_UA=false to keep logins working; symmetric CERTCTL_OIDC_PRELOGIN_REQUIRE_IP=false exists for the IP-side. The legacy-row compat window — pre-migration rows with no stored binding — still passes through unchecked, but that window is bounded by the 10-minute pre-login TTL.

• OIDC provider Advanced fields are now editable in the GUI (Audit 2026-05-11 A-7). The MED-4 row had been DEFERRED to v3 with the rationale "backend already accepts these fields." The verifier hit the GUI and found that the read-only display claimed the values were editable, but the edit form had no inputs — the save handler passed provider.scopes / provider.groups_claim_path / provider.groups_claim_format / provider.iat_window_seconds / provider.jwks_cache_ttl_seconds unchanged from the loaded object. Operators who wanted to bump the IAT window or change the groups-claim path had to drop to curl / MCP and trust the GUI's display matched what they'd set elsewhere. Lying UX. The OIDCProviderDetailPage edit form now has a collapsible Advanced section with five inputs (scopes as a space-separated text field; groups-claim path; groups-claim format select with the backend's string-array / json-path enum; IAT window number input bounded 1–600; JWKS cache TTL number input with floor 60). Client-side validation mirrors the backend Validate rules so common operator mistakes (IAT > 600, JWKS TTL < 60, empty scopes, empty groups-claim-path) reject inline instead of round-tripping a 400. The read-only <dl> also gained the previously-invisible jwks_cache_ttl_seconds row.

• Pre-login cookie Path widened from /auth/oidc/ to / (Audit MED-14 follow-on). Required to satisfy the __Host- prefix's Path=/ rule. The cookie lifetime is unchanged (10 minutes) and only the callback handler consumes it; the wider path scope is harmless.

• RFC 9207 iss URL parameter check on OIDC callback (Audit 2026-05-10 MED-17). When the matched IdP's discovery doc advertises authorization_response_iss_parameter_supported: true, certctl now requires the iss query parameter on /auth/oidc/callback and enforces a constant-time compare against the configured provider's IssuerURL. Mismatch rejects with HTTP 400; the audit row's failure_category distinguishes iss_param_missing / iss_param_mismatch (RFC 9207 leg) from the existing id_token_iss_mismatch (in-token iss claim leg). Closes the mix-up-attack defense for modern Keycloak, Authentik, and public-trust CAs that ship RFC-9207 discovery. Providers that don't advertise support (the majority today) keep pre-fix behavior — back-compat is preserved.

• Auth GUI batch (Audit 2026-05-10 MED-4/7/8/10/11/12 + LOW-1/11/12 + HIGH-10 GUI). New backend endpoints land alongside their GUI consumers: GET /api/v1/auth/users + DELETE /api/v1/auth/users/{id} (auth.user.read / auth.user.deactivate; migration 000045 adds users.deactivated_at plus the two new permissions); GET /api/v1/auth/runtime-config (auth.role.assign) returning a sanitized flat-map of deployed CERTCTL_* values (no secrets leaked — only set/unset booleans and counts); GET /api/v1/auth/oidc/providers/{id}/jwks-status (auth.oidc.list) returning the per-provider verifier counters (refresh count, last refresh / error timestamps, rejected JWS count, RFC 9207 iss-param flag). New UsersPage lists federated identities + soft-deactivates. AuthSettingsPage gains the runtime-config panel. KeysPage's assign-role modal now collects scope_type / scope_id / expires_at. RoleDetailPage's add-permission form gains the same scope picker, and the Delete button is hidden on the 7 default system roles (server already rejected, this is pure UX). AuthProvider renders a sticky red demo-mode banner when auth_type=none. actor-demo-anon rows on KeysPage already had buttons disabled.

• 11 new MCP tools (Audit 2026-05-10 MED-13). Approval workflow (certctl_approval_list / _get / _approve / _reject), break-glass credential admin (certctl_breakglass_list / _set_password / _unlock / _remove), bootstrap status + consume (certctl_bootstrap_status / _consume), and audit category filter (certctl_audit_list_with_category). All route through the existing HTTP client so server-side permission gates fire unchanged. certctl_bootstrap_consume's tool description carries an explicit "NEVER WIRE THIS TO AUTONOMOUS OPERATION" warning — a leaked bootstrap token mints a fresh admin API key bypassing every other access-control gate, so the tool is for one-shot manual operator invocation only.

• JWKS auto-refresh on cache-miss (Audit 2026-05-10 MED-6). When the IdP rotates its signing key between pre-login + callback, the cached JWKS no longer contains the kid referenced by the inbound ID token's JWS header. Pre-fix, the verify failed with a generic error and the operator had to manually call POST /api/v1/auth/oidc/providers/{id}/refresh. The service now detects the kid-not-in-cache shape (isKidMismatchError) and runs a one-shot RefreshKeys (evict cache → re-fetch discovery + JWKS → re-run alg-downgrade defense) before retrying the verify exactly once. Bounded recovery: a second failure surfaces as ErrJWKSUnreachable per the original branches; no retry loop. A separate matcher (isKidMismatchError) is intentionally narrow so generic signature failures don't trigger refresh.

• OIDC provider test endpoint (Audit 2026-05-10 MED-5). New POST /api/v1/auth/oidc/test dry-runs an OIDC provider configuration without persisting: fetches the discovery doc, runs the alg-downgrade defense, detects RFC 9207 iss-parameter advertisement, and confirms JWKS reachability. Returns TestDiscoveryResult{discovery_succeeded, jwks_reachable, supported_alg_values, iss_param_supported, errors[]} so the GUI (forthcoming) can render per-check status rows. Per-leg failures ride in the response body's errors array; only a malformed request body trips 400. Gate: auth.oidc.create. Audit row auth.oidc_provider_tested carries the success/failure summary.

• Pre-login UA / source-IP binding on OIDC callback (Audit 2026-05-10 MED-16). RFC 9700 §4.7.1 defense against stolen-pre-login-cookie replay by a different browser / source. Migration 000044_prelogin_uaip adds client_ip + user_agent to oidc_pre_login_sessions; values captured at /auth/oidc/login are constant-time compared at /auth/oidc/callback. Mismatches return HTTP 400 with audit failure_category = prelogin_ua_mismatch or prelogin_ip_mismatch. Two operator escape hatches: CERTCTL_OIDC_PRELOGIN_REQUIRE_UA and CERTCTL_OIDC_PRELOGIN_REQUIRE_IP (both default true) — operators on enterprise proxies that rewrite UA, or dual-stack v4/v6 environments where source IP routinely flips, can disable the affected leg. The binding column is persisted even when enforcement is off, so retroactive forensics remain possible. Empty values on either side pass through (rolling-deploy + headless-proxy compat).

v2.1.0 - Auth Bundles 1 + 2: RBAC primitive + OIDC SSO + sessions ⚠️

SECURITY: AUDIT YOUR API KEYS.

Bundle 1 ships role-based authorization. Every existing API key configured via CERTCTL_API_KEYS_NAMED (or the legacy CERTCTL_AUTH_SECRET) is mapped to the r-admin role on the first upgrade boot so existing automation keeps working unchanged. Most keys do NOT need full admin power; downgrade them before tagging the next release.

Recommended post-upgrade flow:

# 1. List every key with its current role:
certctl-cli auth keys list

# 2. Walk an interactive prompt that downgrades each key:
certctl-cli auth keys scope-down

# 3. Or get a heuristic suggestion based on 30 days of audit history:
certctl-cli auth keys scope-down --suggest
certctl-cli auth keys scope-down --suggest --apply   # applies the suggestion

# 4. Or drive scope-down from a JSON config (Helm post-upgrade hook):
certctl-cli auth keys scope-down --non-interactive ./scope-down.json

The synthetic actor-demo-anon actor (used when CERTCTL_AUTH_TYPE=none is configured) is system-managed and excluded from the prompt loop.

What else changed in v2.1.0:

• Audit 2026-05-10 CRIT-1 closure — wire-layer RBAC enforcement. The Bundle 1 + Bundle 2 audit surfaced that the permission catalogue was enforced on ~24 admin-only routes only; the bulk of state-changing routes (POST /api/v1/certificates, PUT /api/v1/profiles/{id}, DELETE /api/v1/issuers/{id}, POST /api/v1/agents/{id}/csr, even POST /api/v1/auth/roles + POST /api/v1/auth/keys/{id}/roles) had no rbacGate wrap. A r-viewer Bearer was essentially r-admin minus five fine-grained verbs at the wire layer (CWE-862). This release wraps every state-changing + read endpoint with rbacGate (global scope) or rbacGateScoped (per-profile / per- issuer scope-bound grants), and adds an AST-level CI guard (TestRouterRBACGateCoverage) that fails when a new route is registered without enforcement. Catalogue extended via migration 000039 with 30 permissions covering cert.edit, job.*, approval.*, policy.*, team.*, owner.*, notification.*, discovery.*, network_scan.*, healthcheck.*, digest.*, verification.*, stats.read, metrics.read. AUDIT YOUR KEYS (the scope-down call-out above) now translates to real reduction in blast radius. Auditor pin preserved at exactly {audit.read, audit.export}.

• RBAC primitive shipped. tenants, roles, permissions, role_permissions, actor_roles tables (migration 000029); 33-permission canonical catalogue; 7 default roles (admin, operator, viewer, agent, mcp, cli, auditor); per-handler permission gates via auth.RequirePermission middleware (replaces the legacy IsAdmin boolean check on the 5 admin-only handlers).

• Day-0 admin bootstrap. Set CERTCTL_BOOTSTRAP_TOKEN on a fresh deploy and POST a single curl call against /api/v1/auth/bootstrap to mint the first admin API key; one-shot, never logged, and locks closed once any admin actor exists. Migration 000031 ships the api_keys table that stores the SHA-256 hash; the plaintext is shown in the response body once and never persisted.

• Auditor role split. New auditor role holds only audit.read

  • audit.export. Compliance reviewers can read the audit trail without holding mutation power. Migration 000032 adds audit_events.event_category so auditors can filter to authentication-related events specifically.

• /v1/auth/check enrichment. Response now includes the actor's standing roles and effective permissions, so the GUI gates affordances from a single fetch on app boot.

• Approval-bypass closure. Edits to a profile that has (or would have) RequiresApproval=true now route through the ApprovalService two-person integrity gate (Phase 9). Migration 000033 adds approval_kind + payload to issuance_approval_requests so cert-issuance and profile-edit approvals share the same workflow. Same-actor self-approve is rejected with ErrApproveBySameActor for both kinds. Closes the flip-flop loophole where an admin could disable approval, mutate, re-enable. Documented at docs/reference/profiles.md.

• GUI: Roles / API Keys / Auth Settings / Approvals queue. Four new pages under /auth/* consume /v1/auth/me for permission-aware rendering. The Approvals queue blocks self-approve at the client layer (Approve/Reject buttons hidden when requested_by == current actor_id) on top of the server-side enforcement. AuditPage gains a category filter (cert_lifecycle / auth / config) for the auditor view.

• MCP server gains 12 RBAC tools. Operators driving certctl from Claude / VS Code / any MCP client get parity with the GUI

  • CLI. Each tool routes through the same HTTP handler; permission gates fire server-side.

• OpenAPI catalogues every new route. Every Bundle 1 endpoint ships with an operationId; the parity test guards against drift.

• Coverage gates. internal/auth/ and internal/service/auth/ now have ≥85% coverage floors in .github/coverage-thresholds.yml. The 12-path negative-test list from the Bundle 1 prompt is fully covered (path #12 deferred with in-tree TODO).

• Protocol-endpoint allowlist pinned at three layers. The middleware bypass (auth.IsProtocolEndpoint), the router-level AuthExemptRouterRoutes constant, and a new phase12_protocol_allowlist_test.go AST scan all guard against accidentally wrapping ACME / SCEP / EST / OCSP / CRL routes in rbacGate.

• Bundle 2: OIDC + sessions + back-channel logout + break-glass. Auth Bundle 2 ships in the same v2.1.0 release. Operators get OIDC SSO support for Keycloak / Authentik / Okta / Auth0 / Microsoft Entra ID / Google Workspace (via Keycloak broker), HMAC-signed session cookies with idle/absolute timeouts + CSRF defense, back-channel logout per OpenID Connect Back-Channel Logout 1.0, and a default-OFF break-glass admin path with Argon2id passwords for SSO-broken incidents. API-key auth keeps working unchanged alongside; existing automation needs no changes. Migration walkthrough at docs/migration/oidc-enable.md; per-IdP setup guides at docs/operator/oidc-runbooks/index.md.

• OIDC token validation pinned at three layers. Algorithm allow-list (RS256/RS512/ES256/ES384/EdDSA only) with HS-family + none rejected at the service-layer sentinel; IdP-downgrade-attack defense at provider creation AND every JWKS RefreshKeys (intersects the IdP's advertised id_token_signing_alg_values_supported against the allow- list, rejects providers that advertise weak algs even before any token is signed); OIDC Core §3.1.3.7 re-verification of iss / aud / azp / at_hash (REQUIRED-when-access_token-present per Phase 3 tightening of the spec MAY → MUST) / exp / iat window / nonce constant-time-compare. PKCE-S256 mandatory; plain rejected. Single-use state + nonce via atomic DELETE...RETURNING on consume.

• Session cookies use length-prefixed HMAC. The cookie wire format is v1.<session_id>.<signing_key_id>.<base64url-no-pad(HMAC-SHA256)> with HMAC input len:sid:len:kid (NOT bare-concat) to defeat concatenation collisions. HttpOnly + Secure + SameSite=Lax default; SameSite=Strict configurable via CERTCTL_SESSION_SAMESITE. Idle timeout 1h / absolute 8h defaults; scheduler GC sweeps expired rows hourly. Signing keys rotate via the new RotateSigningKey primitive; the old key stays valid for CERTCTL_SESSION_SIGNING_KEY_RETENTION (default 24h) so existing cookies validate during rollover.

• CSRF defense via double-submit-cookie + hashed-token-on-row. Plaintext CSRF token in the JS-readable certctl_csrf cookie (intentionally HttpOnly=false for the GUI to echo into the X-CSRF-Token header); SHA-256 hash on the session row; subtle.ConstantTimeCompare in the new CSRFMiddleware. API-key actors are CSRF-exempt (no session row in context).

• OIDC client_secret encrypted at rest. AES-256-GCM v3 blob format (magic 0x03 + salt(16) + nonce(12) + ciphertext+tag) using the existing CERTCTL_CONFIG_ENCRYPTION_KEY. Encryption invariant pinned by an integration test asserting ciphertext != plaintext + v3 blob shape + round-trip recovery + wrong-passphrase fails.

• OIDC first-admin bootstrap. New CERTCTL_BOOTSTRAP_ADMIN_GROUPS

  • CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID env vars: the first OIDC-authenticated user with a matching group claim becomes admin per tenant. Coexists with the Bundle 1 env-var-token bootstrap; the admin-existence probe ensures only one wins. Audit row (bootstrap.oidc_first_admin) on every grant.

• Break-glass admin (default-OFF). New CERTCTL_BREAKGLASS_ENABLED env var (default false). When enabled, the local Argon2id-password admin path bypasses OIDC + group-claim layers — intended ONLY for SSO-broken incidents. Argon2id with OWASP 2024 params (m=64 MiB, t=3, p=4); lockout after 5 failures (configurable); constant-time across all failure paths via verifyDummy; surface invisibility (HTTP 404 on every endpoint when disabled, NOT 403). WARN log at server boot when enabled. WebAuthn/FIDO2 second factor pairing on the v3 roadmap (Decision 12).

• GUI: OIDC Providers + Group → Role Mappings + Sessions + login buttons. Four new pages under /auth/* consume the Bundle 2 API surface. Login page renders one "Sign in with X" button per configured OIDC provider (in addition to the API-key form, which remains as a fallback for Bearer-mode + break-glass paths). Sessions page exposes own-sessions + admin all-actors view. Every actionable element is permission-gated server-side via auth.oidc.* and auth.session.* perms; client-side hide is UX layer. Logout button in the sidebar fires POST /auth/logout to clear the session server-side before redirecting to login.

• MCP server gains 11 OIDC + session tools. certctl_auth_list_oidc_providers, _get_oidc_provider, _create_oidc_provider, _update_oidc_provider, _delete_oidc_provider, _refresh_oidc_provider, _list_group_mappings, _add_group_mapping, _remove_group_mapping, _list_sessions, _revoke_session. Operator-facing MCP tool count goes 12 (Bundle 1 RBAC) → 23 across the auth surface. Total MCP tool count: grep -cE 'mcp\.AddTool\(' internal/mcp/tools*.go ≈ 150.

• Per-IdP runbooks: 6 production-tier setup guides at docs/operator/oidc-runbooks/. Each runbook follows a consistent five-section layout (Prerequisites / IdP-side config / certctl-side config / Verification / Troubleshooting + Validation checklist with operator sign-off line). Keycloak is the canonical reference; Authentik / Okta / Auth0 / Entra ID / Google Workspace document the IdP-specific deltas (Auth0's namespaced custom claims; Entra ID's group OBJECT IDs; Google Workspace's missing-groups-claim limitation

  • the recommended Keycloak broker pattern).

• Threat model extended. docs/operator/auth-threat-model.md ships 5 new "Defenses Bundle 2 ships" subsections + 8 new threat- catalogue subsections (OIDC token forgery / session hijacking / IdP compromise / back-channel logout failure modes / group-claim manipulation / bootstrap risks / break-glass risks / token-leak hygiene). 6 new SQL-shaped operator-facing checks. New "Threats Bundle 2 does NOT close" section enumerating the 8 v3-backlog items (WebAuthn / JIT elevation / SAML / multi-tenant activation / HSM-FIPS / OIDC RP-initiated logout / Playwright / per-IdP external-tester sign-off).

• Performance baselines documented. docs/operator/auth-benchmarks.md ships four benchmarks with measured baselines on a 4 vCPU / 8 GiB / Postgres 16 / Go 1.25 floor: BenchmarkSession_SteadyState p99 5 µs (target < 1 ms; 200× under), BenchmarkSession_ColdProcess p99 7.1 ms (target < 10 ms), BenchmarkOIDC_SteadyState p99 1.5 ms (target < 5 ms), BenchmarkOIDC_ColdCache operator-runs against live Keycloak via make benchmark-auth-coldcache.

• Standards + RFC implementation table. docs/reference/auth-standards-implemented.md ships 13 RFC / standard rows + 14 CWE rows with concrete file paths

  • negative-test anchors per row. NOT a compliance-mapping doc per the operator's 2026-05-05 retired-compliance-docs decision; the doc explicitly says "build the framework mapping yourself against the rows here using the framework-mapping methodology your audit firm prescribes; this project does not own that mapping."

• Coverage gates held at floor 90 across all four Bundle 2 packages. internal/auth/oidc/ 93.7%, internal/auth/session/ 94.9%, internal/auth/breakglass/ 91.5%, internal/auth/user/domain/ 96.4%. NO held-low-with-rationale entry — the Phase 13 prompt's anti-Bundle-1-mistake rule held. Bundle 1's existing 85% floors for internal/auth/ + internal/service/auth/ stay 85 (already-shipped-and-accepted) per the prompt's explicit inheritance rule.

• Multi-tenant query CI guard. New scripts/ci-guards/multi-tenant-query-coverage.sh (ratchet-style, baseline 32 at v2.1.0 close): greps every SELECT/UPDATE/DELETE in internal/repository/postgres/ against 10 tenant-aware tables, fails on regression OR improvement (forces the operator to lift / lower the baseline visibly). Forward-compat protection so a future Bundle 3 / managed-service multi-tenant activation can flip the switch without finding silent tenant-data-leak bugs in shipped queries.

• Phase 10 Keycloak testcontainers integration test. New build-tag- gated suite at internal/auth/oidc/testfixtures/ + integration_keycloak_test.go drives the full OIDC flow against a live Keycloak container booted by testcontainers-go. 5-test matrix: discovery + JWKS load, full PKCE auth-code happy path with HTTP form scraping, logout-revokes- session, JWKS rotation, unmapped-groups-fails-closed. Reuses one container across the matrix to amortize the 60-90s boot. Optional Okta smoke test (build-tagged integration && okta_smoke) for live tenant validation. New Makefile targets: make keycloak-integration-test

  • make okta-smoke-test + make benchmark-auth-coldcache.

• OpenAPI surface extended. New cookieAuth security scheme (apiKey/cookie/certctl_session) alongside the existing bearerAuth. 13 new Bundle 2 endpoints across the OIDC + session

  • group-mapping CRUD surface; 4 break-glass endpoints with surface-invisibility framing. The N-bundle-2-security-empty-preserved CI guard locks the security: [] opt-out count at ≥ 14 so existing public endpoints stay public.

• Bundle-1-only compat regression CI guard. New scripts/ci-guards/bundle-1-compat-regression.sh asserts the load-bearing invariants that protect the Bundle-1-only-deploy case (session middleware defers-to-next, CSRF passthrough on missing session row, ChainAuthSessionThenBearer wired, public OIDC routes in AuthExempt allowlist, AuthInfo guards on OIDCProvidersResolver != nil). Sibling bundle-1-to-2-upgrade-regression.sh asserts the upgrade-path invariants (migrations 000034..000038 are CREATE TABLE IF NOT EXISTS

  • BEGIN/COMMIT-wrapped + no DROP TABLE / ALTER...DROP COLUMN against 19 protected Bundle-1 tables + ON CONFLICT DO NOTHING on permission seed).

Migration ordering, idempotency, and downgrade are documented in docs/migration/api-keys-to-rbac.md (API-key → RBAC, Bundle 1) and docs/migration/oidc-enable.md (API-key → OIDC, Bundle 2). The threat model lives at docs/operator/auth-threat-model.md. Day-2 RBAC operations live at docs/operator/rbac.md. RFC + CWE evidence at docs/reference/auth-standards-implemented.md.

v2.0.68 - Image registry path changed ⚠️

Image registry path changed. Starting this release, container images publish to ghcr.io/certctl-io/certctl-server and ghcr.io/certctl-io/certctl-agent. Existing pulls from ghcr.io/shankar0123/certctl-{server,agent}:<tag> continue to work for previously-published tags (the registry never deletes images), but the :latest tag at the old path stops moving forward at this release. Update your docker pull paths, docker-compose.yml image: keys, or Helm image.repository values to receive future updates. Old git clone / git push / install-script / API URLs continue to redirect forever - only the container-registry path changed.

This is the only operator-action-required change in v2.0.68. Other changes in this release are cosmetic URL refreshes after the GitHub-org transfer from shankar0123/certctl to certctl-io/certctl (HTTP redirects mean no other operator action is required) plus an internal contextcheck lint fix in the agent. Full commit list is on the GitHub release page.

---

certctl no longer maintains a hand-edited per-version changelog. Per-release notes are auto-generated from commit messages between consecutive tags.

Where to find what changed in a given release:

• GitHub Releases - every tag has an auto-generated "What's Changed" section pulled from the commits between that tag and the previous one, plus per-release supply-chain verification instructions (Cosign / SLSA / SBOM).
• git log <prev-tag>..<this-tag> --oneline - same content, locally.

Why no hand-edited CHANGELOG.md:

certctl is solo-developed and pushes directly to master. Maintaining a hand-edited CHANGELOG meant the file drifted (entries piled into [unreleased] and never got promoted to per-version sections when tags were cut). A stale CHANGELOG is worse than no CHANGELOG - it signals abandoned maintenance to security-conscious operators doing diligence.

The auto-generated release notes work here because commit messages follow a descriptive convention: <area>: <summary> with a longer body for non-trivial changes (see git log v2.0.50..HEAD for the established pattern). Anyone reading the GitHub Releases page can see exactly what landed in each version without depending on the author to manually update a separate file.

For the historical record: earlier versions (pre-v2.2.0 and the [2.2.0] tag itself) had a hand-edited CHANGELOG. That content is preserved in git history at the v2.2.0 tag.
