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• **Issue**: Outdated @anthropic-ai/claude-code version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

┌─────────────────────────────────────────┐
│              API BOUNDARY               │
├─────────────────────────────────────────┤
│  Input Validation & Authentication      │

└─────────────────────────────────────────┘

**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**

// Zod-based validation
const TaskInputSchema = z.object({
  taskId: z.string().uuid(),
  content: z.string().max(10000),
  agentType: z.enum(["security", "core", "integration"]),
});

**Path Sanitization**

// 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**

// 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
