• 🔎 Security Analysis udrcrafts_security_analysis.csv
• 📊 Remediation Roadmap Visualization (attached below)

---

📌 Critical Issues (Highest Priority)

1. Password Security

• Issue: Passwords stored in plain text.
• Location: e-commerce-backend/index.js line 126
• Severity: 🔴 Critical
• Status: Not Implemented
• Fix:
  • Use bcrypt or Argon2 for hashing.
  • Enforce strong password policies.
  • Implement salted hashing before storing credentials.

---

2. JWT Secret Handling

• Issue: Hardcoded JWT secret (secret_ecom).
• Location: e-commerce-backend/index.js line 50, 162
• Severity: 🔴 Critical
• Status: Basic - Hardcoded Secret
• Fix:
  • Store secrets in environment variables.
  • Rotate JWT secrets periodically.
  • Enable token expiration and refresh token mechanism.

---

3. Data Encryption

• Issue: No encryption for sensitive data at rest or in transit.
• Severity: 🔴 Critical
• Status: Not Implemented
• Fix:
  • Enable HTTPS/TLS across all endpoints.
  • Encrypt sensitive DB fields (payment info, PII).
  • Use AES-256 or similar strong encryption standards.

---

⚠️ High Priority Issues

4. Input Validation

• Issue: No input validation on API endpoints.
• Location: All API endpoints
• Severity: 🟠 High
• Fix:
  • Implement server-side validation (e.g., Joi, Zod).
  • Sanitize inputs to prevent XSS/SQLi.

---

5. Database Security

• Issue: Direct MongoDB queries without sanitization.
• Location: index.js multiple locations
• Severity: 🟠 High
• Fix:
  • Use parameterized queries.
  • Apply role-based DB access controls.
  • Escape all user-provided inputs.

---

6. CSRF Protection

• Issue: Missing CSRF protection.
• Location: All forms and API calls
• Severity: 🟠 High
• Fix:
  • Implement CSRF tokens (synchronizer or double-submit cookies).
  • Enforce SameSite cookie attributes.

---

🟡 Medium Priority Issues

• Authentication: JWT implemented but lacks refresh tokens and advanced policies.
• Error Handling: Missing structured error responses (could leak stack traces).
• CORS Config: Needs stricter origin validation.
• Env Variables: Inconsistent handling across services.

---

📊 Visual Roadmap

---

✅ Next Steps

• Hash all stored passwords
• Secure JWT handling with env secrets
• Implement DB input sanitization
• Add CSRF protection middleware
• Apply strong encryption for sensitive data
• Strengthen CORS, Error Handling, and Env Config
