🔒 Security Audit Summary - MidStream Repository

Date: October 31, 2025 Overall Security Score: 🔴 CRITICAL (28/100) Status: IMMEDIATE ACTION REQUIRED

🚨 CRITICAL ISSUES REQUIRING IMMEDIATE ACTION

1. EXPOSED API KEYS AND CREDENTIALS - CRITICAL ⚠️

Location: /workspaces/midstream/.env.local

Status: ❌ TRACKED BY GIT AND PUBLICLY ACCESSIBLE

Exposed Credentials (15+ API keys):

✗ OpenRouter API Key: sk-or-v1-33bc9dcfcb3107aa...
✗ Anthropic API Key: sk-ant-api03-A4quN8ZhLo8CIXWE...
✗ HuggingFace API Key: hf_DjHQclwWGPzwStPm...
✗ Google Gemini API Key: AIzaSyBKMO_UCkhn...
✗ E2B API Keys (2): e2b_79b115201a8cb697..., sk_e2b_6ed0679d1c20...
✗ Supabase Keys (2): sbp_ea6f6af965185721..., JWT token
✗ Genesis Password & Hash
✗ Genesis Darknet Private Key: 2a97a18d1d1aac9c...
✗ Flow Nexus Session Token (JWT)
✗ Flow Nexus Password: password123
✗ Requesty API Key
✗ Crates.io API Key
✗ Perplexity API Key: pplx-VBynPwKCV6WUQGUf...

Impact:

Unauthorized API usage (financial liability)
Complete access to E2B sandbox infrastructure
Supabase database access
User account compromise
Potential data breach
Cryptocurrency wallet compromise (darknet private key)

IMMEDIATE ACTIONS (Complete within 24 hours):

Rotate ALL exposed API keys immediately:

# Revoke and regenerate:
- OpenRouter dashboard → API Keys → Revoke
- Anthropic Console → API Keys → Delete
- HuggingFace Settings → Access Tokens → Revoke
- Google Cloud Console → Credentials → Delete
- E2B Dashboard → API Keys → Regenerate
- Supabase Project Settings → API → Reset keys
- Crates.io Account Settings → API Access → Revoke
- Perplexity AI → API Keys → Delete

Remove .env.local from repository:

# Remove from tracking
git rm --cached .env.local
git commit -m "Security: Remove exposed credentials"
git push

Purge from Git history (REQUIRED - file exists in history):

# WARNING: This rewrites history - coordinate with team
git filter-branch --force --index-filter \
  "git rm --cached --ignore-unmatch .env.local" \
  --prune-empty --tag-name-filter cat -- --all

# Force push to all branches
git push origin --force --all
git push origin --force --tags

# Clean local repository
rm -rf .git/refs/original/
git reflog expire --expire=now --all
git gc --prune=now --aggressive

Revoke Genesis User Access:
- Change password: 74059e26c4e06bf283064961d56ca57e0e33dcfb31a6d136e771a3ba4a2dda66
- Regenerate darknet private key: 2a97a18d1d1aac9c29f69f5e136b5c5c3634cc52af3294da27ee21ef07f46417
- Invalidate Flow Nexus session token
Monitor for unauthorized usage:
- Check OpenRouter usage logs
- Review Anthropic API usage
- Audit E2B sandbox creation logs
- Check Supabase database access logs
- Review Crates.io publish history

🔴 HIGH SEVERITY VULNERABILITIES

2. Dependency Vulnerabilities - HIGH

Summary: 14 vulnerabilities across 7 packages

Critical Issues:

axios ≤0.30.1: CSRF, SSRF, DoS vulnerabilities (CVSS 7.5)
Missing package-lock.json in 5 packages (unable to audit)
Outdated critical dependencies: axios, ws, vitest, wasm-pack

Immediate Actions:

# Update vulnerable dependencies
cd /workspaces/midstream/npm
npm update axios ws

cd /workspaces/midstream/AIMDS
npm update vitest esbuild

# Generate missing lockfiles
cd /workspaces/midstream/lean-agentic-js
npm install

cd /workspaces/midstream/wasm/www
npm install

Details: See /workspaces/midstream/docs/SECURITY_VULNERABILITY_REPORT.md

3. Wildcard CORS Policy - HIGH

Location: npm/src/streaming.ts:165-167

Issue:

res.setHeader('Access-Control-Allow-Origin', '*');

Risk: CSRF attacks, credential theft, unauthorized access

Fix:

const allowedOrigins = process.env.ALLOWED_ORIGINS?.split(',') || ['http://localhost:3000'];
const origin = req.headers.origin;
if (origin && allowedOrigins.includes(origin)) {
  res.setHeader('Access-Control-Allow-Origin', origin);
}

4. Missing Session Validation - HIGH

Location: npm/src/openai-realtime.ts:73-98

Issue: Session IDs stored but never validated or expired

Fix:

interface Session {
  id: string;
  createdAt: number;
  expiresAt: number;
  userId?: string;
}

const SESSION_TTL = 3600000; // 1 hour

function validateSession(sessionId: string): boolean {
  const session = activeSessions.get(sessionId);
  if (!session || Date.now() > session.expiresAt) {
    activeSessions.delete(sessionId);
    return false;
  }
  return true;
}

5. No Authorization Layer - HIGH

Location: npm/src/mcp-server.ts:68-99

Issue: MCP server accepts tool calls without permission checks

Fix: Implement RBAC (Role-Based Access Control)

6. Path Traversal Vulnerability - HIGH

Location: npm/src/cli.ts:252-284

Issue: User-provided paths not sanitized

Fix:

import path from 'path';

function sanitizePath(userPath: string, baseDir: string): string {
  const resolved = path.resolve(baseDir, userPath);
  if (!resolved.startsWith(baseDir)) {
    throw new Error('Path traversal detected');
  }
  return resolved;
}

🟡 MEDIUM SEVERITY ISSUES

7. Missing Input Sanitization (8 instances)

JSON parsing without validation
Unvalidated environment variables
Direct database queries (potential injection)

8. Weak Docker Security

Hardcoded Grafana password: admin
No secrets management
Environment file mounting

9. Documentation Contains Partial Keys

Files with truncated API keys in AIMDS/docs/
Risk of social engineering attacks

✅ SECURITY STRENGTHS

Positive Findings:

✅ No hardcoded API keys in source code (except .env.local)
✅ Helmet.js security headers configured
✅ Rate limiting implemented (100 req/window)
✅ Parameterized SQL queries (no SQL injection)
✅ HTTPS/WSS for external connections
✅ TypeScript type safety
✅ Zod schema validation
✅ No eval() usage
✅ Graceful shutdown handling
✅ GitHub Actions use secrets properly
✅ .gitignore properly configured (now)
✅ No private key files (.pem, .key) in repository
