Checklist Verification (PRD Tasks)

Backend Security (worker1)

• VULN-001: Stripe Webhook Required — ✅ Implemented in webhook.js:7-12. Server exits if STRIPE_WEBHOOK_SECRET is not set. Fallback to JSON.parse removed.
• VULN-003: JWT Secret Validation — ✅ Implemented in index.js:5-8. Validates JWT_SECRET exists and is ≥32 characters at startup.
• VULN-008: npm audit fix — ✅ Verified qs dependency is not in package.json (resolved via express dependency updates)

Auth Security (worker2)

• VULN-004: OTP Rate Limiting — ✅ Implemented in auth.js:11-36:
  • verifyOtpLimiter: 5 attempts per 15 min per email/IP
  • requestOtpLimiter: 3 attempts per 15 min per email/IP
  • Both applied correctly to /verify-otp (line 172) and /request-otp (line 83)

Input Validation (worker3)

• VULN-005: Input Validation — ✅ Implemented using express-validator:
  • beneficiaries.js: POST (lines 366-380), PATCH (lines 584-604) - name, phone, address, customName validated
  • stripe.js: All POST endpoints validated - userId, beneficiaryId, priceId, email, etc.
  • invitations.js: POST (lines 245-262), PATCH (lines 644-649) - email, role enum, beneficiaryId validated

Security Implementation Quality

All security fixes follow best practices:

1. Startup validation — Server refuses to start without critical secrets (JWT_SECRET, STRIPE_WEBHOOK_SECRET)
2. Rate limiting — Properly keyed by email (prevents IP bypassing via VPN), with sensible limits
3. Input validation — Uses industry-standard express-validator with proper error messages
4. Documentation — Doppler guide is comprehensive and actionable
