We release security updates for the following versions:

Note: Version 1.0.0 and later will follow long-term support (LTS) policy.

We take security seriously. If you discover a security vulnerability, please follow these guidelines:

• ❌ Create a public GitHub issue
• ❌ Discuss the vulnerability publicly
• ❌ Exploit the vulnerability beyond verification

• ✅ Report privately via email to: security@your-domain.com or adrian207@gmail.com
• ✅ Provide detailed information about the vulnerability
• ✅ Allow reasonable time for us to address the issue
• ✅ Work with us to verify the fix

Send an email to security@your-domain.com or adrian207@gmail.com with:

Required Information:

• Description of the vulnerability
• Steps to reproduce
• Affected versions
• Potential impact assessment
• Any suggested fixes (optional)

Optional Information:

• Proof of concept (if safe to share)
• Environment details
• Screenshots or logs

We will acknowledge receipt within 48 hours.

Our security team will:

• Verify the vulnerability
• Assess severity and impact
• Develop a fix
• Test the fix
• Prepare security advisory

Timeline: Typically 7-14 days depending on severity.

Once fixed:

• Security patch released
• Security advisory published
• CVE assigned (if applicable)
• Credit given to reporter (unless requested otherwise)

• Critical/High: Private disclosure, patch released ASAP
• Medium/Low: Coordinated disclosure after patch release
• Full disclosure: 90 days after initial report (or after patch, whichever is sooner)

Workload Identity Federation:

• No secrets stored in configuration
• Automatic token rotation
• Native cloud identity integration
• Least privilege access

• Review access logs regularly
• Update dependencies promptly

Monitoring:

• Enable security alerts
• Monitor for suspicious activity
• Review audit logs
• Track failed authentication attempts
• Monitor API rate limits

Code Security:

• Never commit secrets or credentials
• Use environment variables for configuration
• Validate all inputs
• Sanitize all outputs
• Follow secure coding guidelines
• Conduct security code reviews

Dependencies:

• Keep dependencies updated
• Review dependency security advisories
