NPM Dependency Vulnerabilities

Before & After

Phase	Critical	High	Moderate	Total	Status
Before	6	0	13	19	❌ Unsafe
After	0	3*	3*	6	⚠️ Dev-only

*Remaining 6 vulnerabilities are in build tools only (dev dependencies), not production code.

Fixed Vulnerabilities (100% Resolved)

Critical Fixes

CVE	Package	Issue	Action
Arbitrary Code Execution	underscore (1.12.0)	Template injection in `_.template()`	✅ Removed via msi-packager elimination
Arbitrary Code Execution	lodash (4.17.20)	Multiple prototype pollution + command injection	✅ Removed via msi-packager elimination
Unsafe Random Function	form-data (2.5.3)	Unsafe boundary generation for multipart requests	✅ Fixed via pkg upgrade
SSRF Vulnerability	request (2.88.2)	Server-Side Request Forgery in deprecated library	✅ Fixed via pkg upgrade

Moderate/High Build Tool Fixes

Package	Vol	Severity	Resolution
msi-packager	34 pkgs	Critical	✅ Removed
nomnom	1	Critical	✅ Removed (msi-packager dep)
xmlbuilder	1	Moderate	✅ Removed (msi-packager dep)
js-yaml	1	Moderate	✅ Updated to 3.14.2
pkg	2	Moderate	✅ Updated to 6.14.1
wix-msi	-	High	✅ Updated to latest

Remaining Vulnerabilities (Dev-Only)

These only affect build tools, not runtime or users.

Package	Severity	Via	Impact	Mitigation
axios	HIGH	wix-msi	CSRF/SSRF in MSI generation	Use trusted CI/CD only
sharp	HIGH	wix-msi	libwebp CVE (image processing)	Use trusted CI/CD only
pkg	MODERATE	Direct dev dep	Local privilege escalation	Don't run builds as admin
js-yaml	MODERATE	xmlbuilder2	Prototype pollution	Dev-only, no user input
xmlbuilder2	MODERATE	-	Prototype pollution	Dev-only, no user input

Why safe: These tools only run on developer machines or CI/CD pipelines during build—never in production or user environments.

Code-Level Security Findings

CRITICAL Issues (Fix Recommended)

1. PowerShell Command Injection

File: src/alertHandler.js (lines 208–215)
Issue: Alert title/areas interpolated into PowerShell without XML escaping
Risk: Attacker-controlled alert title could execute arbitrary PowerShell commands

Example Attack:

Title: "test" ; rm C:\Users\... ; echo "

Fix:

const escapeXml = (str) => 
  String(str)
    .replace(/&/g, '&amp;')
    .replace(/</g, '&lt;')
    .replace(/>/g, '&gt;')
    .replace(/"/g, '&quot;')
    .replace(/'/g, '&apos;');

const title = escapeXml(alert.title || 'Alert');
const areas = escapeXml(matchedAreas.join(', '));
// Use in PowerShell code...

2. Unsafe Sound File Path

File: src/alertHandler.js (line 261)
Issue: Unquoted path in PowerShell could fail with spaces/special characters

Fix: Quote all PowerShell path variables

`(New-Object Media.SoundPlayer '${soundPath}').PlaySync()`

IMPORTANT Issues (Recommended)

3. No Input Validation on Config API

File: src/configServer.js (POST /api/config)
Issue: Accepts any JSON without schema validation
Risks:
- browserUrl can be set to file://, javascript:, or malicious domains
- pollInterval could be 0 (DOS) or extremely high
- areas array unbounded (memory exhaustion)
- alertCooldown could be negative or millions

Fix: Add validation middleware

function validateConfig(config) {
  const errors = [];
  
  if (!Array.isArray(config.areas) || config.areas.length > 50) {
    errors.push('areas must be array with ≤50 items');
  }
  
  const pollInt = parseInt(config.pollInterval);
  if (isNaN(pollInt) || pollInt < 1000 || pollInt > 60000) {
    errors.push('pollInterval must be 1000–60000 ms');
  }
  
  try {
    const url = new URL(config.browserUrl);
    if (!url.protocol.startsWith('https')) {
      errors.push('browserUrl must use https://');
    }
  } catch {
    errors.push('browserUrl must be valid URL');
  }
  
  return errors;
}

4. Missing Security Headers

File: src/configServer.js
Issue: No CSP, X-Frame-Options, X-Content-Type-Options headers
Risk: Config panel could be framed or XSS'd if accessed from compromised browser

Fix:

app.use((req, res, next) => {
  res.setHeader('X-Content-Type-Options', 'nosniff');
  res.setHeader('X-Frame-Options', 'DENY');
  res.setHeader('X-XSS-Protection', '1; mode=block');
  res.setHeader('Referrer-Policy', 'no-referrer');
  next();
});

5. Sensitive Data in Logs

Files: src/logger.js, src/main.js (lines 14–16)
Issue: Logs contain user's LOCALAPPDATA path and process CWD
Risk: If logs are shared or exposed, reveals user's home directory

Fix: Redact environment variables

log.info('LOCALAPPDATA:', process.env.LOCALAPPDATA ? '<USER_APPDATA>' : 'N/A');

6. Alert History Exposes Location Data

File: src/alertHandler.js → /api/history endpoint
Issue: Full alert history with areas and timestamps exposed via HTTP
Risk: If config server is exposed, attacker can see where/when user was alerted
Fix: Implement optional history retention limit and encryption

7. No Rate Limiting

File: src/configServer.js
Issue: Config endpoints have no rate limiting
Risk: Local DOS via rapid API calls (though localhost-only)

Mitigation: Add express-rate-limit

import rateLimit from 'express-rate-limit';
const limiter = rateLimit({ windowMs: 60000, max: 100 });
app.use(limiter);

MINOR Issues

Category	Issue	Impact
No CSRF Protection	POST endpoints lack CSRF tokens	Low (localhost)
Browser URL Not Validated	User can set to `file://` URLs	Low (localhost, user-controlled)
Inconsistent Logging	Some code uses `console.log` instead of `log` module	Low (missing persistent logs)

Threat Model & Risk Assessment

Attack Surface Analysis

Component	Attack Vector	Likelihood	Impact	Risk
Alert API (oref.org.il)	Compromised upstream API	Low	High	MEDIUM
Config Server (127.0.0.1)	Man-in-the-middle (localhost)	Very Low	High	LOW
PowerShell Execution	Malicious alert title	Low	High	MEDIUM
File I/O (config.json)	Local filesystem access	Low	Medium	LOW
Notifications	Native API vulnerabilities	Very Low	Low	VERY LOW

Scope Limitations

localhost-only: Config server is bound to 127.0.0.1, not exposed to network
Local application: Runs only on user's machine; no server component
User-controlled config: Areas and settings are user-configured; untrusted only from compromised upstream API
Trusted code: All code is first-party; no third-party script injection

Recommendations

Immediate (High Priority)

Fix PowerShell injection – Implement XML escaping for alert titles/areas
Add input validation – Validate all config POST parameters
Add security headers – Prevent framing and XSS in config panel
Redact logs – Remove user paths from startup log output

Effort: ~30 minutes
Risk Reduction: HIGH → Removes all critical code vulnerabilities

Medium-term (Recommended)

Rate limiting – Add express-rate-limit middleware
History retention – Implement max record limit and optional encryption
Consistent logging – Replace console.log with log module everywhere
Update dependencies – Monitor for pkg/wix-msi upstream patches

Effort: ~1 hour
Risk Reduction: MEDIUM → Adds defense-in-depth

Long-term (Optional)

Replace pkg – Consider esbuild + standalone Node for build pipeline
CI/CD hardening – Ensure builds only run in trusted environments
Security testing – Add automated security linting (eslint-plugin-security)
Audit logging – Log all config changes with user context
