About V3 Security Overhaul

V3 Security Overhaul is a Claude Code skill for coordinating security work on claude-flow v3. It covers vulnerability remediation, threat modeling, testing, and secure coding patterns.

Key features

  1. 01Coordinate security-focused agents
  2. 02Address dependency vulnerabilities
  3. 03Replace weak password hashing
  4. 04Validate inputs and sanitize paths
  5. 05Avoid shell interpretation in commands

Use cases

  1. 01Plan a v3 threat model
  2. 02Remediate critical vulnerabilities
  3. 03Add security tests and validation
  4. 04Review command execution and path handling

Install

Copy the command and run it in a terminal.

V3 Security Overhaul

What This Skill Does

Orchestrates comprehensive security overhaul for claude-flow v3, addressing critical vulnerabilities and establishing security-first development practices using specialized v3 security agents.

Quick Start

# Initialize V3 security domain (parallel)
Task("Security architecture", "Design v3 threat model and security boundaries", "v3-security-architect")
Task("CVE remediation", "Fix CVE-1, CVE-2, CVE-3 critical vulnerabilities", "security-auditor")
Task("Security testing", "Implement TDD London School security framework", "test-architect")

Critical Security Fixes

CVE-1: Vulnerable Dependencies
npm update @anthropic-ai/claude-code@^2.0.31
npm audit --audit-level high
CVE-2: Weak Password Hashing
// ❌ Old: SHA-256 with hardcoded salt
const hash = crypto.createHash('sha256').update(password + salt).digest('hex');

// ✅ New: bcrypt with 12 rounds
import bcrypt from 'bcrypt';
const hash = await bcrypt.hash(password, 12);
CVE-3: Hardcoded Credentials
// ✅ Generate secure random credentials
const apiKey = crypto.randomBytes(32).toString('hex');

Security Patterns

Input Validation (Zod)
import { z } from 'zod';

const TaskSchema = z.object({
  taskId: z.string().uuid(),
  content: z.string().max(10000),
  agentType: z.enum(['security', 'core', 'integration'])
});
Path Sanitization
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;
}
Safe Command Execution
import { execFile } from 'child_process';

// ✅ Safe: No shell interpretation
const { stdout } = await execFile('git', [userInput], { shell: false });

Success Metrics

  • Security Score: 90/100 (npm audit + custom scans)
  • CVE Resolution: 100% of critical vulnerabilities fixed
  • Test Coverage: >95% security-critical code
  • Implementation: All secure patterns documented and tested
