Complete security architecture overhaul for claude-flow v3. Addresses critical CVEs (CVE-1, CVE-2, CVE-3) and implements secure-by-default patterns. Use for security-first v3 implementation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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
```bash
# 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
```bash
npm update @anthropic-ai/claude-code@^2.0.31
npm audit --audit-level high
```
### CVE-2: Weak Password Hashing
```typescript
// ❌ 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
```typescript
// ✅ Generate secure random credentials
const apiKey = crypto.randomBytes(32).toString('hex');
```

How to install
mdr add spencermarx/open-code-review/V3 Security Overhaul@sha256:4123b78d5a2d68aeThe line at the top of this page pins the label git:20260304.1a73d7f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
