Code Guardian Report is committed to maintaining the highest security standards for our users. This document outlines our security practices, vulnerability reporting process, and guidelines for secure usage of the application.

We take security seriously and encourage responsible disclosure of any vulnerabilities you may discover. This policy applies to all Code Guardian Report services, including the web application, API endpoints, and any associated infrastructure.

We release patches for security vulnerabilities. Which versions are eligible for receiving such patches depends on the CVSS v3.0 Rating:

• Critical (CVSS 9.0-10.0): Patches released within 48 hours
• High (CVSS 7.0-8.9): Patches released within 7 days
• Medium (CVSS 4.0-6.9): Patches released within 14 days
• Low (CVSS 0.1-3.9): Patches included in next scheduled release

Please report (suspected) security vulnerabilities to security@example.com or through GitHub's private vulnerability reporting feature. You will receive a response from us within 48 hours. If the issue is confirmed, we will release a patch as soon as possible depending on complexity but historically within a few days.

1. GitHub Private Reporting (Preferred): Use GitHub's private vulnerability reporting feature to submit a security advisory.
