Please do not report security vulnerabilities through public GitHub issues.

Instead, please report them via:

• Email: [Create an issue with "SECURITY" prefix]
• Private vulnerability disclosure: Use GitHub's private vulnerability reporting feature

Please include the following information:

• Type of issue (e.g. buffer overflow, SQL injection, cross-site scripting, etc.)
• Full paths of source file(s) related to the manifestation of the issue
• The location of the affected source code (tag/branch/commit or direct URL)
• Any special configuration required to reproduce the issue
• Step-by-step instructions to reproduce the issue
• Proof-of-concept or exploit code (if possible)
• Impact of the issue, including how an attacker might exploit it

ShadowCheck implements several security measures:

• Parameterized queries to prevent SQL injection
• Connection pooling with limits
• Encrypted credential storage via system keyring
• Database user with minimal required privileges

• Rate limiting on all API endpoints
• Input validation and sanitization
• CORS configuration
• Content Security Policy headers

• No hardcoded secrets in source code
• Environment-based configuration
• Secure session management
• Data validation on all inputs

• PostgreSQL with PostGIS for secure geospatial operations
• Express.js with security middleware
• Compression and security headers
• Error handling without information disclosure

We follow responsible disclosure practices:

1. Report received and acknowledged within 48 hours
2. Initial assessment within 7 days
3. Regular updates on progress
4. Public disclosure coordinated after fix is available
5. Credit given to security researchers (if desired)

Security updates are prioritized and released as soon as possible. Users are encouraged to:

• Keep dependencies updated
• Monitor security advisories
• Use strong database credentials
• Enable HTTPS in production
• Regularly backup data

For security-related questions or concerns, please create an issue with the "SECURITY" label.
