- Open redirect / client-side XSS (app-base.js): the post-login `redirect`
read from the URL fragment was assigned straight to window.location. Add a
same-origin guard (safeInternalPath) that rejects absolute URLs,
protocol-relative "//host"/"/\\host", and scheme targets like
"javascript:". Apply it in consumeTokenFragment and logInRedirect.
- Server-side defense in depth: sanitize `redirect` when storing OidcState
and when building the callback fragment (utils/safe_redirect.js, shared +
unit-tested).
- Missing rate limiting: throttle the unauthenticated auth endpoints
(/login, /oidc/start, /oidc/callback) with express-rate-limit (60/IP/15m).
Set `trust proxy: 1` so req.ip reflects the real client behind OpenResty.
Adds test/unit/safe_redirect.test.js; unit suite 77 pass.

Authentication previously implied full authorization: any valid token
could manage every host, DNS provider, domain, and user. This adds SSO
login and a per-domain rights model.
OIDC login (authorization_code + PKCE):
- conf.oidc + conf.auth blocks; clientSecret in (gitignored) secrets.js.
- utils/oidc.js (state/PKCE, code exchange, userinfo) using global fetch.
- models/oidc_state.js: short-lived state store, auto-expiring via
model-redis 1.5 per-key TTL.
- routes/auth.js: GET /auth/oidc/start + /auth/oidc/callback; JIT-provisions
a local user, mints an AuthToken carrying the SSO groups, hands the token to
the browser via a URL fragment. "Log in with SSO" button on the login page.
Authorization (groups + app overrides, per-domain, with ownership):
- models/grant.js + utils/roles.js (pure, unit-tested): effective rights from
conf.auth (admin users/groups, group->role map), Grant records
(user|group -> global|domain -> viewer|manager|admin), and ownership
(created_by). Roles rank admin > manager(owner) > viewer.
- AuthToken stores session groups; middleware/auth.js exposes req.groups.
- middleware/authz.js: requireAdmin, requireDomainRole(minRole, resolveDomain),
filterViewable. Applied across routes: host mutations need manager on the
host's domain; reads are filtered to visible domains; DNS providers, user
management, and grant management are global-admin-only; certs need viewer.
- routes/grant.js: admin CRUD for grants. Anti-lockout via conf.auth.adminUsers
plus migrations/grant_bootstrap.js.
Frontend: /me returns effective rights; nav gates Users/Grants to admins;
grants management page; OIDC token-fragment handling in app-base.js.
Tests: utils/roles and utils/oidc unit-tested (no redis); wired into the test
scripts. Full suite 89 pass. Also verified end-to-end against redis (grant
resolution, middleware allow/deny/403, list filtering) and the OIDC pure flow.
