🔒 Security Checklist - PromptCraft

✅ Security Audit Completed: 25 November 2025

🛡️ Environment Variables Security

✅ Protected Files

  • .env.local - IGNORED ✓ (Never committed to Git)
  • .env - IGNORED ✓
  • .env*.local - IGNORED ✓
  • All environment files in .gitignore ✓

✅ Public vs Private Variables

Public (Safe to expose to browser):

  • ✅ NEXT_PUBLIC_SUPABASE_URL - Safe (public URL)
  • ✅ NEXT_PUBLIC_SUPABASE_ANON_KEY - Safe (anon key with RLS)
  • ✅ NEXT_PUBLIC_SITE_URL - Safe (public URL)

Private (Server-side only):

  • ✅ DATABASE_URL - PROTECTED (not prefixed with NEXTPUBLIC)
  • ✅ OPENROUTER_API_KEY - PROTECTED (server-side only)
  • ✅ MIDTRANS_SERVER_KEY - PROTECTED (server-side only)

🔐 Database Security

✅ Row Level Security (RLS)

  • RLS enabled on all tables ✓
  • Users can only access their own data ✓
  • Public content properly filtered ✓
  • Policies tested and verified ✓

✅ Tables Protected

  • prompts - User-specific access only
  • templates - Published templates public, drafts private
  • purchases - User-specific access only
  • favorites - User-specific access only
  • reviews - Public read, user-specific write
  • profiles - Public read, user-specific write

🚫 No Sensitive Data Exposed

✅ Code Clean

  • No hardcoded API keys ✓
  • No hardcoded passwords ✓
  • No console.log with sensitive data ✓
  • No commented-out credentials ✓

✅ Files Not Committed

  • .env.local not in repository ✓
  • node_modules/ ignored ✓
  • .next/ build files ignored ✓
  • Database files ignored ✓
  • IDE files ignored ✓

🔒 Authentication Security

✅ Supabase Auth

  • Email verification enabled
  • Password requirements enforced
  • Session management secure
  • OAuth properly configured
  • CSRF protection (built-in Supabase)

✅ Best Practices

  • No passwords stored in code
  • Secure session storage (localStorage)
  • Auto-refresh tokens
  • Proper sign-out flow

🌐 API Security

✅ API Routes Protected

  • Server-side API keys not exposed
  • Input validation on all endpoints
  • Error messages don't leak sensitive info
  • Rate limiting considerations documented

✅ Client-Side Security

  • No sensitive operations in client code
  • All database operations through Supabase RLS
  • No direct database queries from client

📝 Code Quality

✅ Production Ready

  • No debug console.logs ✓
  • Error handling implemented ✓
  • Loading states for all async operations ✓
  • Proper error messages (user-friendly) ✓

✅ Dependencies

  • All dependencies up to date
  • No known vulnerabilities
  • Only necessary packages installed

🚀 Deployment Security

✅ Pre-Deployment Checklist

  • Environment variables set in Vercel
  • OAuth redirect URLs updated for production
  • Supabase RLS policies verified
  • HTTPS enforced in production
  • CORS properly configured
  • Rate limiting enabled (if applicable)

✅ Post-Deployment

  • Test authentication flow
  • Test database operations
  • Monitor error logs
  • Check for exposed secrets
  • Verify RLS policies working

📋 Files Security Status

✅ Safe to Commit

  • ✅ README.md - Documentation only
  • ✅ package.json - No secrets
  • ✅ next.config.js - No secrets
  • ✅ tailwind.config.js - No secrets
  • ✅ .env.example - Template only (no real values)
  • ✅ All .md files - Documentation only
  • ✅ All source code files - No hardcoded secrets

🚫 Never Commit

  • 🚫 .env.local - CONTAINS SECRETS
  • 🚫 .env - CONTAINS SECRETS
  • 🚫 node_modules/ - Dependencies
  • 🚫 .next/ - Build artifacts
  • 🚫 Any file with real API keys

🔍 Security Scan Results

✅ Automated Checks

# No hardcoded secrets found ✓
# No console.log with sensitive data ✓
# All environment variables properly prefixed ✓
# .gitignore comprehensive ✓

✅ Manual Review

  • All API calls reviewed
  • All database queries reviewed
  • All authentication flows reviewed
  • All environment variables reviewed

🛠️ Security Recommendations

Implemented ✅

  1. ✅ Use environment variables for all secrets
  2. ✅ Enable RLS on all Supabase tables
  3. ✅ Implement proper authentication
  4. ✅ Validate all user inputs
  5. ✅ Use HTTPS in production
  6. ✅ Comprehensive .gitignore

Future Enhancements 📋

  1. Add rate limiting on API routes
  2. Implement CAPTCHA on sign-up
  3. Add 2FA (Two-Factor Authentication)
  4. Set up security monitoring
  5. Regular security audits
  6. Implement CSP (Content Security Policy)
  7. Add API request logging
  8. Set up automated vulnerability scanning

🚨 Critical Security Rules

❌ NEVER DO THIS:

// ❌ WRONG - Hardcoded API key
const apiKey = "sk-1234567890abcdef";

// ❌ WRONG - Exposing server key to client
const NEXT_PUBLIC_SERVER_KEY = "secret-key";

// ❌ WRONG - Console logging sensitive data
console.log("User password:", password);

✅ ALWAYS DO THIS:

// ✅ CORRECT - Use environment variables
const apiKey = process.env.OPENROUTER_API_KEY;

// ✅ CORRECT - Server-side only (no NEXT_PUBLIC_)
const serverKey = process.env.SERVER_KEY;

// ✅ CORRECT - Don't log sensitive data
console.log("Authentication successful");
