Security Review Summary

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

Quick Overview

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: [email protected]
   • 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

# 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
