# Security Review Summary

**Date:** 2026-01-03  
**Version:** v2.7.47  
**Status:** ⚠️ NOT PRODUCTION READY - Critical fixes required

---

## Quick Overview

| Metric | Count |
|--------|-------|
| **Total Vulnerabilities** | 18 |
| **Critical** | 3 🔴 |
| **High** | 7 🟠 |
| **Medium** | 5 🟡 |
| **Low** | 3 🟢 |
| **Dependency Issues** | 13 (7 high) |

---

## Critical Issues (Fix Immediately)

1. **Vulnerable Dependencies** - 7 high-severity npm packages
   - `@anthropic-ai/claude-code` < 2.0.31 (Command injection)
   - `@modelcontextprotocol/sdk` < 1.24.0 (DNS rebinding)
   - **Fix:** `npm update && npm audit fix`

2. **Weak Password Hashing** - Uses SHA-256 instead of bcrypt
   - File: `src/api/auth-service.ts:580`
   - **Fix:** Implement bcrypt with salt

3. **Hardcoded Credentials** - Default admin password in code
   - Username: `admin@claude-flow.local`
   - Password: `admin123` (in public repo!)
   - **Fix:** Generate random passwords on first run

---

## High-Priority Issues (Fix Before v3.0)

4. **Command Injection** - Shell execution without sanitization
   - Files: `src/cli/commands/hook.ts`, `src/utils/error-recovery.ts`
   - **Fix:** Remove `shell: true`, add input validation

5. **Path Traversal** - No validation on file paths
   - File: `src/cli/commands/task.ts:67`
   - **Fix:** Implement path validation utility

6. **Insufficient Input Validation** - Config commands accept any input
   - File: `src/cli/commands/config.ts`
   - **Fix:** Add schema validation with Zod

7. **Weak Token Generation** - Uses Math.random()
   - File: `src/mcp/auth.ts:375`
   - **Fix:** Use crypto.randomBytes()

---

## What's Working Well ✅

1. **SQL Injection Prevention** - All queries use parameterized statements
2. **Timing-Safe Comparisons** - Proper implementation in auth
3. **Key Redaction System** - Automatic secret sanitization
4. **GitHub CLI Wrapper** - Good input validation
5. **Permission System** - Hierarchical access control

---

## Action Plan

### Week 1: Critical Fixes
```bash
# 1. Update dependencies
npm update @anthropic-ai/claude-code@^2.0.31
npm update @modelcontextprotocol/sdk@^1.24.0
npm audit fix --force

# 2. Install bcrypt
npm install bcrypt @types/bcrypt

# 3. Run tests
npm test
```

### Week 2-3: High Priority
- Fix command injection vulnerabilities
- Add path traversal protection
- Implement input validation
- Fix weak token generation

### Week 4+: Medium/Low Priority
- Add audit logging
- Implement secret management
- Set up OAuth 2.0
- Configure SIEM integration

---

## Security Score

**Before Fixes:** 45/100 (Failing)
- Critical vulnerabilities present
- Weak authentication
- Insufficient input validation

**After Critical Fixes:** 70/100 (Acceptable)
- No critical vulnerabilities
- Strong authentication
- Basic protection in place

**After All Fixes:** 90/100 (Production Ready)
- Comprehensive security controls
- Defense in depth
- Continuous monitoring

---

## Recommended Tools

- **SAST:** SonarQube, Semgrep
- **Dependency Scanning:** npm audit, Snyk
- **Secret Scanning:** git-secrets, truffleHog
- **Container Security:** Trivy
- **Runtime Protection:** OWASP ZAP
