Critical Vulnerabilities (Immediate Action Required)

🔴 VULN-001: Command Injection via Tool Installation

CVSS 9.8 | CRITICAL

Location: src/utils/installer.ts:73-105

Problem:
The runCommand() function executes commands with shell: true, allowing arbitrary command injection through tool installation parameters.

Attack Vector:

// Malicious tool definition
installCommand: 'npm install package; rm -rf /'

Fix:

// SECURE VERSION - Remove shell execution
import { execa } from 'execa';

const ALLOWED_COMMANDS = ['npm', 'npx', 'pip', 'python'];

export async function runCommand(command: string): Promise<string> {
  const parts = command.split(' ');
  const cmd = parts[0];

  if (!ALLOWED_COMMANDS.includes(cmd)) {
    throw new Error(`Command '${cmd}' not allowed`);
  }

  const result = await execa(cmd, parts.slice(1));
  return result.stdout;
}

---

🔴 VULN-002: Path Traversal in Configuration Files

CVSS 9.1 | CRITICAL

Location: src/utils/config.ts:35-59

Problem:
No validation on directory paths allows reading/writing arbitrary files via path traversal (../../../etc).

Attack Vector:

loadConfig('../../../../etc/passwd')
saveConfig(maliciousData, '../../../root/.bashrc')

Fix:

// SECURE VERSION
import { resolve, normalize } from 'path';

const ALLOWED_BASE_DIR = process.cwd();

export function getConfigPath(dir: string = process.cwd()): string {
  const absoluteDir = resolve(dir);

  if (!absoluteDir.startsWith(ALLOWED_BASE_DIR)) {
    throw new Error('Access denied: Path outside project directory');
  }

  if (dir.includes('..')) {
    throw new Error('Path traversal detected');
  }

  return join(absoluteDir, CONFIG_FILE);
}

---

High Priority Vulnerabilities

🟠 VULN-003: Overly Permissive CORS Configuration

CVSS 7.5 | HIGH

Location: src/mcp/sse.ts:20-29

Problem:
CORS set to Access-Control-Allow-Origin: * allows any website to interact with the MCP server.

Impact: Malicious websites can trigger MCP actions while server runs locally.

Fix:

const ALLOWED_ORIGINS = ['http://localhost:3000'];

app.use((req, res, next) => {
  const origin = req.headers.origin;
  if (origin && ALLOWED_ORIGINS.includes(origin)) {
    res.setHeader('Access-Control-Allow-Origin', origin);
  }
  next();
});

---

🟠 VULN-004: Missing Rate Limiting

CVSS 7.5 | HIGH

Location: src/mcp/sse.ts:14-73

Problem:
No rate limiting, connection limits, or request size restrictions enable DoS attacks.

Fix:

import rateLimit from 'express-rate-limit';

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000,
  max: 100,
  message: 'Too many requests'
});

app.use(express.json({ limit: '1mb' }));
app.use('/rpc', limiter);

---

🟠 VULN-005: Insufficient Security Logging

CVSS 7.2 | HIGH

Location: Multiple files

Problem:
No audit trail for security events (command execution, file operations, MCP requests). Errors expose internal details.

Fix:

import winston from 'winston';

const securityLogger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.File({ filename: 'security-audit.log' })
  ]
});

// Log all security-relevant events
securityLogger.info('command_execution', {
  command: sanitizedCommand,
  user: process.env.USER,
  timestamp: new Date().toISOString()
});

---

Medium Priority Vulnerabilities

🟡 VULN-006: Information Disclosure

CVSS 5.3 | MEDIUM

Location: src/mcp/sse.ts:32-91

Endpoints expose server version, capabilities, and internal structure without authentication.

Fix: Remove version info, require authentication for /health and / endpoints.

---

🟡 VULN-007: Unsafe JSON Parsing

CVSS 4.3 | MEDIUM

Location: src/mcp/stdio.ts:25, src/utils/config.ts:51

JSON parsing without validation enables prototype pollution and DoS.

Fix: Use ajv for schema validation, secure-json-parse for safe parsing.

---

Low Priority Vulnerabilities

🟢 VULN-008: Missing Security Headers

CVSS 3.7 | LOW

Location: src/mcp/sse.ts:13-17

No security headers (CSP, X-Frame-Options, etc.) configured.

Fix:

import helmet from 'helmet';
app.use(helmet());

---

Dependency Analysis

✅ NPM Audit: CLEAN

• Total Dependencies: 268 (129 prod, 140 dev)
• Known Vulnerabilities: 0
• Outdated Packages: Express 4.18.2 → 4.19.2 (update recommended)

Code Examples for Quick Fixes

1. Secure Command Execution

// Install: npm install execa
import { execa } from 'execa';

const ALLOWED = ['npm', 'npx', 'pip', 'python'];

async function runCommand(cmd: string): Promise<string> {
  const [command, ...args] = cmd.split(' ');
  if (!ALLOWED.includes(command)) {
    throw new Error('Command not allowed');
  }
  const { stdout } = await execa(command, args);
  return stdout;
}

2. Path Validation

import { resolve } from 'path';

function validatePath(inputPath: string): string {
  const basePath = process.cwd();
  const fullPath = resolve(basePath, inputPath);

  if (!fullPath.startsWith(basePath) || inputPath.includes('..')) {
    throw new Error('Invalid path');
  }
  return fullPath;
}

3. Rate Limiting

import rateLimit from 'express-rate-limit';

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 min
  max: 100 // requests per window
});

app.use('/rpc', limiter);

4. Security Headers

import helmet from 'helmet';

app.use(helmet({
  contentSecurityPolicy: true,
  frameguard: { action: 'deny' },
  hsts: { maxAge: 31536000 }
}));
