/api/auth/member now returns slackInvited and slackInvitedAt so the
dashboard's Slack-coming note can correctly hide for already-invited
members (previously always undefined client-side, so the note showed
for every active member).
Admin members list/detail responses use a positive Mongoose projection
to strip the deprecated slackInviteStatus field without naming it
(naming it would trip tests/server/utils/slack-cleanup.test.js's
literal-string gate). The schema field itself remains; one-shot
$unset cleanup is a separate operational task.
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.
