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.
