fix: the application exposes public api endpoints (/... in config.js

[anupamme]

Summary

Fix high severity security issue in config.js.

Vulnerability

Field	Value
ID	V-002
Severity	HIGH
Scanner	multi_agent_ai
Rule	V-002
File	config.js:1
Assessment	Likely exploitable

Description: The application exposes public API endpoints (/version, /oauth/authorize, /metrics/nsfs_stats, /) without implementing rate limiting. The config.js file and web server configuration do not include any rate limiting middleware or configuration.

Evidence

Exploitation scenario: An attacker sends a large number of HTTP requests to public endpoints like GET /version or GET /oauth/authorize using a tool like Apache Bench or a botnet.

Scanner confirmation: multi_agent_ai rule V-002 flagged this pattern.

Production code: This file is in the production codebase, not test-only code.

Threat Model Context

This is a web service - vulnerabilities in request handlers are directly exploitable by remote attackers.

Changes

• config.js
• src/server/web_server.js

Behavior Preservation

The change is scoped to 2 files on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.

Security Invariant

Property: The security boundary is maintained under adversarial input

Regression test

const config = require('./config');
const assert = require('assert');

describe("Rate limiting configuration must be present for public endpoints", () => {
  const endpoints = [
    '/version',
    '/oauth/authorize',
    '/metrics/nsfs_stats',
    '/'
  ];

  endpoints.forEach(endpoint => {
    it(`should have rate limiting configured for ${endpoint}`, () => {
      // Check that config has rate limiting settings
      assert(config, 'Config should be defined');
      
      // Check for rate limiting middleware configuration
      const hasRateLimitConfig = 
        config.RATE_LIMIT_ENABLED !== undefined ||
        config.rate_limit !== undefined ||
        config.middleware?.includes('rateLimit') ||
        config.public_endpoints?.[endpoint]?.rate_limit !== undefined;
      
      assert(
        hasRateLimitConfig,
        `Rate limiting must be configured for public endpoint: ${endpoint}`
      );
    });
  });
});

This test guards against regressions — it's useful independent of the code change above.

📝 Walkthrough

Walkthrough

Added public API rate-limit defaults and an in-memory IP-based limiter. The limiter protects /version, /oauth/authorize, /metrics/nsfs_stats, and the root redirect route. Exceeded requests receive HTTP 429.

Changes

Public API rate limiting

Layer / File(s)	Summary
Rate-limit configuration and middleware config.js, src/server/web_server.js	Added a 60-second request window, a 100-request limit per IP, and middleware that returns HTTP 429 after the limit is exceeded.
Protected route wiring src/server/web_server.js	Applied the limiter to the version, OAuth authorization, NSFS metrics, and root redirect routes.

Estimated code review effort: 3 (Moderate) | ~20 minutes
