🚨 Reporting a Vulnerability

We appreciate the security community's efforts in helping us maintain a secure platform. If you discover a security vulnerability in LearnMate, please follow these guidelines:

How to Report

DO NOT open a public GitHub issue for security vulnerabilities.

Instead, please report security issues through one of these channels:

  1. Email (Preferred): security@learnmate.ai
  2. Private GitHub Advisory: Use GitHub's private vulnerability reporting feature
  3. Direct Message: Contact maintainers directly on GitHub

What to Include

Please provide the following information in your report:

  • Description: Clear description of the vulnerability
  • Impact: Potential impact and severity assessment
  • Steps to Reproduce: Detailed steps to reproduce the issue
  • Affected Versions: Which versions are affected
  • Proof of Concept: Code or screenshots demonstrating the vulnerability (if applicable)
  • Suggested Fix: Your recommendations for fixing the issue (optional)
  • Your Details: Name and contact information for acknowledgment (optional)

📅 Response Timeline

We are committed to responding to security reports promptly:

Timeline Action
Within 24 hours Initial acknowledgment of your report
Within 72 hours Preliminary assessment and severity classification
Within 7 days Detailed response with our evaluation and action plan
Within 30 days Security patch release (for confirmed vulnerabilities)
Within 90 days Public disclosure (after fix is deployed)

Severity Classification

We use the following severity levels:

  • 🔴 Critical: Immediate threat to user data or system integrity (e.g., remote code execution, authentication bypass)
  • 🟠 High: Significant security risk (e.g., privilege escalation, SQL injection)
  • 🟡 Medium: Moderate security concern (e.g., XSS, CSRF)
  • 🟢 Low: Minor security issue (e.g., information disclosure, rate limiting bypass)

✅ What to Expect

If the Vulnerability is Accepted

  1. Acknowledgment: We'll confirm the vulnerability and classify its severity
  2. Timeline: We'll provide an estimated timeline for the fix
  3. Updates: Regular updates on our progress (at least weekly)
  4. Credit: You'll be credited in our security acknowledgments (if desired)
  5. Patch Release: We'll release a security patch and notify users
  6. Public Disclosure: After users have had time to update (typically 30-90 days)

If the Vulnerability is Declined

  1. Explanation: We'll provide a detailed explanation of why we don't consider it a vulnerability
  2. Alternative: If applicable, we'll suggest filing a feature request or bug report
  3. Discussion: We're open to further discussion if you disagree with our assessment

🛡️ Security Measures

LearnMate implements multiple layers of security:

Frontend Security

  • ✅ Content Security Policy (CSP) headers
  • ✅ XSS protection through React's built-in escaping
  • ✅ HTTPS-only in production
  • ✅ Secure cookie handling
  • ✅ Input sanitization and validation
  • ✅ No sensitive data in client-side storage

Backend Security

  • ✅ JWT authentication with secure token storage
  • ✅ bcrypt password hashing (10+ rounds)
  • ✅ Rate limiting (100 requests per 15 minutes per IP)
  • ✅ Helmet.js for security headers
  • ✅ CORS with whitelist configuration
  • ✅ Express-validator for input validation
  • ✅ MongoDB injection prevention through Mongoose
  • ✅ Environment variable protection
  • ✅ Secure session management

AI Service Security

  • ✅ Input sanitization for ML models
  • ✅ Rate limiting on AI endpoints
  • ✅ Model file integrity checks
  • ✅ Logging and monitoring
  • ✅ Isolated service architecture
  • ✅ Resource usage limits

Infrastructure Security

  • ✅ Regular dependency updates
  • ✅ Automated security scanning (Dependabot)
  • ✅ HTTPS/TLS encryption
  • ✅ Database encryption at rest
  • ✅ Regular backups
  • ✅ Access control and principle of least privilege

🔍 Known Security Considerations

Current Limitations

We're transparent about current security limitations:

  1. API Rate Limiting: Currently set to 100 requests per 15 minutes; may need tuning for production scale
  2. File Upload: Not yet implemented; will require careful validation when added
  3. Password Reset: Uses email-based reset; consider adding 2FA in the future
  4. Session Management: JWT tokens don't have revocation without database lookups

Planned Security Enhancements

  • Two-factor authentication (2FA)
  • OAuth integration (Google, GitHub)
  • Advanced anomaly detection
  • API key rotation system
  • Enhanced audit logging
  • Security headers hardening
  • Automated penetration testing
