DO NOT open a public GitHub issue for security vulnerabilities. Instead, please report security issues directly to:

📧 opensource@telekom.de

Or use GitHub's private security advisory feature:

🔒 Report a Vulnerability

Please include:

• A clear description of the vulnerability
• Steps to reproduce (if applicable)
• Affected component(s) and version(s)
• Potential impact and severity
• Any suggested fixes (if you have them)

We take all security reports seriously and will respond within 48 hours to acknowledge receipt. We will keep you updated on the investigation and remediation progress.

The Auth Operator project is committed to security by design:

• RBAC Management - Secure generation and binding of Kubernetes RBAC resources
• Webhook Authorization - Real-time authorization enforcement via Kubernetes webhooks
• Least Privilege - Access is restricted to explicitly configured roles only
• Certificate Management - Automatic certificate rotation for webhook TLS

This project uses multiple security tools to maintain code quality:

• CodeQL - Static analysis for security vulnerabilities
• Dependabot - Dependency vulnerability tracking
• golangci-lint - Go code quality and security linting
• REUSE - License compliance verification

We actively monitor and update dependencies to address security issues:

• Go dependencies are kept up-to-date with security patches
• Container images are built on secure base images
• All dependencies are vendored or pinned to specific versions

Auth Operator handles sensitive data:

• RBAC Resources - Stored as Kubernetes resources with RBAC controls
• Webhook Secrets - Certificate and key material stored in Kubernetes Secrets
• Audit Logs - Available for security monitoring and compliance
• TLS/HTTPS - All webhook communication uses encrypted connections

1. Network Security - Deploy behind firewall/network policies
2. RBAC Configuration - Properly configure Kubernetes RBAC on the cluster
3. TLS Certificates - Ensure webhook certificates are valid and properly managed
4. Secret Management - Protect access to webhook secrets

• RoleDefinitions - Review all RoleDefinitions before deployment
• BindDefinitions - Carefully validate group and subject bindings
• WebhookAuthorizers - Ensure webhook endpoints are properly secured
• Monitoring - Enable metrics and monitor for anomalies
• Logging - Forward logs to SIEM for security monitoring

• Images - Use container image scanning in your registry
• RBAC - Follow least privilege principle for operator service account
• Network Policies - Restrict network access to authorized sources
• Pod Security - Use Pod Security Standards (restricted profile recommended)
• Service Accounts - Limit permissions to minimum required

In case of a confirmed security vulnerability:

1. Acknowledgment - We will acknowledge receipt within 48 hours
2. Assessment - We will evaluate severity and affected versions
3. Disclosure Coordination - We will coordinate a timeline for public disclosure
4. Patch Release - A patch will be released as soon as possible
5. Notification - Users will be notified of available updates

We follow responsible disclosure practices:

• Vulnerability reporters are credited unless they request anonymity
• We provide a reasonable time for affected users to update before public disclosure
• We coordinate with security researchers and industry partners
• We maintain a transparent communication policy

This project adheres to:

• OpenSSF Best Practices - Security recommendations from the Open Source Security Foundation
• OWASP Top 10 - Mitigation of common web application vulnerabilities
• CIS Kubernetes Benchmarks - Kubernetes security hardening guidelines
• REUSE Specification - Software license compliance

• README - Installation and configuration overview
• Documentation - Detailed documentation and guides

• Contributing Guidelines - How to contribute securely
• Code of Conduct - Community guidelines

• Kubernetes Security Best Practices
• RBAC Authorization

Only the latest version receives security updates. We recommend:

• Staying on the latest stable release
• Monitoring GitHub releases for security patches
• Testing updates in a staging environment before production deployment
• Subscribing to GitHub notifications for critical security updates
