Follow-up to 208638e. Code review surfaced a few real issues; this
commit addresses them.
- login.post.js now uses the new sendMagicLink util instead of
duplicating the jti/jwt/Resend/logActivity logic. Reduces 60 lines.
- sendMagicLink accepts an optional pre-loaded Member doc, skipping
the redundant findOne when the caller already has one. customer.post.js
passes the just-created/upgraded member, dropping signup from 3
Mongo round-trips to 1 (lookup is gone; jti burn remains).
- sendMagicLink now lowercases the email defensively so callers don't
have to remember.
- rateLimit.js: replaced an effectively-dead eviction line with a
probabilistic sweep (~1% of calls scan and evict keys whose newest
entry has aged out). Caps unbounded Map growth under random-key
spraying.
- reconcile-payments.post.js: 401/403/404 from Helcim now bails out
immediately instead of burning all 3 retry attempts; dry-run
summary filters via the same RECONCILABLE_STATUSES set as apply
mode so counts match.
- Deleted WHAT-comments and section banners per CLAUDE.md no-comment
rule. Kept genuine WHY-comments (validateBeforeSave rationale,
amount-IGNORED-for-tickets, sendConfirmation deliberately-omitted).
Tests: 758/760 passing (unchanged).
- Simplified the magic link email format to plain text for better compatibility.
- Updated the welcome email to use plain text and changed the sender address to match the domain.
- Enhanced event registration email format to plain text, removing HTML styling for a cleaner approach.
- Add centralized Zod schemas (server/utils/schemas.js) and validateBody
utility for all API endpoints
- Fix critical mass assignment in member creation: raw body no longer
passed to new Member(), only validated fields (email, name, circle,
contributionTier) are accepted
- Apply Zod validation to login, profile patch, event registration,
updates, verify-payment, and admin event creation endpoints
- Fix logout cookie flags to match login (httpOnly: true, secure
conditional on NODE_ENV)
- Delete unauthenticated test/debug endpoints (test-connection,
test-subscription, test-bot)
- Remove sensitive console.log statements from Helcim and member
endpoints
- Remove unused bcryptjs dependency
- Add 10MB file size limit on image uploads
- Use runtime config for JWT secret across all endpoints
- Add 38 validation tests (117 total, all passing)
Auth: Add requireAuth/requireAdmin guards with JWT cookie verification,
member status checks (suspended/cancelled = 403), and admin role
enforcement. Apply to all admin, upload, and payment endpoints. Add
role field to Member model.
CSRF: Double-submit cookie middleware with client plugin. Exempt
webhook and magic-link verify routes.
Headers: X-Content-Type-Options, X-Frame-Options, X-XSS-Protection,
Referrer-Policy, Permissions-Policy on all responses. HSTS and CSP
(Helcim/Cloudinary/Plausible sources) in production only.
Rate limiting: Auth 5/5min, payment 10/min, upload 10/min, general
100/min via rate-limiter-flexible, keyed by client IP.
XSS: DOMPurify sanitization on marked() output with tag/attr
allowlists. escapeHtml() utility for email template interpolation.
Anti-enumeration: Login returns identical response for existing and
non-existing emails. Remove 404 handling from login UI components.
Mass assignment: Remove helcimCustomerId from profile allowedFields.
Session: 7-day token expiry, refresh endpoint, httpOnly+secure cookies.
Environment: Validate required secrets on startup via server plugin.
Remove JWT_SECRET hardcoded fallback.
