Pre-launch P0 fixes surfaced by docs/specs/events-functional-test-matrix.md
(Findings 1, 2, 3).
1. Series-pass bypass (Finding 1 / matrix S1 P3): register.post.js now
loads the linked Series when tickets.requiresSeriesTicket is set and
rejects drop-in registration unless series.allowIndividualEventTickets
is true or the user has a valid pass. Data-integrity 500 if the
referenced series is missing.
2. Hidden-event leak (Finding 2 / matrix E11): extract loadPublicEvent
into server/utils/loadEvent.js. All five public event endpoints
([id].get, register, tickets/available, tickets/reserve,
tickets/purchase) now go through the helper, which 404s when
isVisible === false and the requester is not an admin. Admin detection
uses a new non-throwing getOptionalMember() in server/utils/auth.js
(extracted from the pattern already inlined in api/auth/status.get.js).
3. Deadline enforcement + legacy pricing retirement (Finding 3 / matrix
E8): register.post.js and tickets/reserve.post.js delegate gating to
validateTicketPurchase (which already covers deadline, cancelled,
started, members-only, sold-out, and already-registered);
tickets/available.get.js gets an explicit registrationDeadline check.
Legacy pricing.paymentRequired 402 branch removed from register.post.js.
Non-members who register for an event now get a persistent identity:
with consent, a status:"guest" Member is upserted and an auth cookie is
set so the "You're Registered" state survives a page refresh.
Tiered auto-login matches passwordless-auth norms — auto-login is only
safe when the account holds no privileges:
- New email → create guest + cookie
- Returning guest → cookie
- Existing non-guest (active/pending/etc.) → attach ticket only, no
cookie, confirmation email includes a sign-in link
Guests are gated on status === "guest", so admin/middleware code that
keys on status === "active" naturally excludes them. Guests are also
treated as non-members for ticket pricing/validation to prevent picking
up member-only pricing on their second registration.
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.
