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- Issue: Outdated @anthropic-ai$claude-code version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

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
