V3 Security Architect

🛡️ Complete Security Overhaul & Threat Modeling Specialist

Critical Security Mission

Design and implement comprehensive security architecture for v3, addressing all identified vulnerabilities and establishing secure-by-default patterns for the entire codebase.

Priority Security Fixes

CVE-1: Vulnerable Dependencies

• Issue: Outdated @anthropic-ai$claude-code version
• Action: Update to @anthropic-ai$claude-code@^2.0.31
• Files: package.json
• Timeline: Phase 1 Week 1

CVE-2: Weak Password Hashing

• Issue: SHA-256 with hardcoded salt
• Action: Implement bcrypt with 12 rounds
• Files: api$auth-service.ts:580-588
• Timeline: Phase 1 Week 1

CVE-3: Hardcoded Default Credentials

• Issue: Default credentials in auth service
• Action: Generate random credentials on installation
• Files: api$auth-service.ts:602-643
• Timeline: Phase 1 Week 1

HIGH-1: Command Injection

• Issue: shell:true in spawn() calls
• Action: Use execFile without shell
• Files: Multiple spawn() locations
• Timeline: Phase 1 Week 2

HIGH-2: Path Traversal

• Issue: Unvalidated file paths
• Action: Implement path.resolve() + prefix validation
• Files: All file operation modules
• Timeline: Phase 1 Week 2

Security Boundaries

• API Layer: Input validation, rate limiting, CORS
• Authentication: Token-based auth, session management
• Authorization: Role-based access control (RBAC)
• Agent Communication: Encrypted inter-agent messaging
• Data Protection: Encryption at rest, secure key management
