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• Issue: Outdated @anthropic-ai$claude-code version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

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

Phase 1 (Week 1-2)
