# 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- **Issue**: Outdated @anthropic-ai/claude-code version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 Architecture Design
### **Threat Model Domains**
```
┌─────────────────────────────────────────┐
│ API BOUNDARY │
├─────────────────────────────────────────┤
│ Input Validation & Authentication │
├─────────────────────────────────────────┤
│ CORE SECURITY LAYER │
├─────────────────────────────────────────┤
│ Agent Communication & Authorization │
├─────────────────────────────────────────┤
│ STORAGE & PERSISTENCE │
└─────────────────────────────────────────┘
```
### **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
## Secure Patterns Catalog
### **Input Validation**
```typescript
// Zod-based validation
const TaskInputSchema = z.object({
taskId: z.string().uuid(),
content: z.string().max(10000),
agentType: z.enum(['security', 'core', 'integration'])
});
```
### **Path Sanitization**
```typescript
// Secure path handling
function securePath(userPath: string, allowedPrefix: string): string {
const resolved = path.resolve(allowedPrefix, userPath);
if (!resolved.startsWith(path.resolve(allowedPrefix))) {
throw new SecurityError('Path traversal detected');
}
return resolved;
}
```
### **Command Execution**
```typescript
// Safe command execution
import { execFile } from 'child_process';
// ❌ Dangerous: shell injection possible
// exec(`git ${userInput}`, { shell: true });
// ✅ Safe: no shell interpretation
execFile('git', [userInput], { shell: false });
```
## Deliverables
### **Phase 1 (Week 1-2)**
- [ ] **SECURITY-ARCHITECTURE.md** - Complete threat model
- [ ] **CVE-REMEDIATION-PLAN.md** - Detailed fix timeline
- [ ] **SECURE-PATTERNS.md** - Reusable security patterns
- [ ] **THREAT-MODEL.md** - Attack surface analysis
### **Validation Criteria**
- [ ] All CVEs addressed with tested fixes
- [ ] npm audit shows 0 high/critical vulnerabilities
- [ ] Security patterns documented and implemented
- [ ] Threat model covers all v3 domains
- [ ] Security testing framework established
## Coordination with Security Team
### **Security Implementer (Agent #3)**
- Provide detailed implementation specifications
- Review all security-critical code changes
- Validate CVE remediation implementations
### **Security Tester (Agent #4)**
- Supply test specifications for security patterns
- Define penetration testing requirements
- Establish security regression test suite
## Success Metrics
- **Security Score**: 90/100 (npm audit + custom scans)
- **CVE Resolution**: 100% of identified CVEs fixed
- **Test Coverage**: >95% for security-critical code
- **Documentation**: Complete security architecture docs
- **Timeline**: All deliverables within Phase 1
