+# Incident Response Process for **nvm**
+
+## Reporting a Vulnerability
+
+We take the security of **nvm** very seriously. If you believe you’ve found a security vulnerability, please inform us responsibly through coordinated disclosure.
+
+### How to Report
+
+> **Do not** report security vulnerabilities through public GitHub issues, discussions, or social media.
+
+Instead, please use one of these secure channels:
+
+1. **GitHub Security Advisories**
+    Use the **Report a vulnerability** button in the Security tab of the [nvm-sh/nvm repository](https://github.com/nvm-sh/nvm).
+
+2. **Email**
+    Follow the posted [Security Policy](https://github.com/nvm-sh/nvm/security/policy).
+
+### What to Include
+
+**Required Information:**
+- Brief description of the vulnerability type
+- Affected version(s) and components
+- Steps to reproduce the issue
+- Impact assessment (what an attacker could achieve)
+
+**Helpful Additional Details:**
+- Full paths of affected scripts or files
+- Specific commit or branch where the issue exists
+- Required configuration to reproduce
+- Proof-of-concept code (if available)
+- Suggested mitigation or fix
+
+## Our Response Process
+
+**Timeline Commitments:**
+- **Initial acknowledgment**: Within 24 hours
+- **Detailed response**: Within 3 business days
+- **Status updates**: Every 7 days until resolved
+- **Resolution target**: 90 days for most issues
+
+**What We’ll Do:**
+1. Acknowledge your report and assign a tracking ID
+2. Assess the vulnerability and determine severity
+3. Develop and test a fix
+4. Coordinate disclosure timeline with you
+5. Release a security update and publish an advisory and CVE
+6. Credit you in our security advisory (if desired)
+
+## Disclosure Policy
+
+- **Coordinated disclosure**: We’ll work with you on timing
+- **Typical timeline**: 90 days from report to public disclosure
+- **Early disclosure**: If actively exploited
+- **Delayed disclosure**: For complex issues
+
+## Scope
+
+**In Scope:**
+- **nvm** project (all supported versions)
+- Installation and update scripts (`install.sh`, `nvm.sh`)
+- Official documentation and CI/CD integrations
+- Dependencies with direct security implications
+
+**Out of Scope:**
+- Third-party forks or mirrors
+- Platform-specific installs outside core scripts
+- Social engineering or physical attacks
+- Theoretical vulnerabilities without practical exploitation
+
+## Security Measures
+
+**Our Commitments:**
+- Regular vulnerability scanning via GitHub Actions
+- Automated security checks in CI/CD pipelines
+- Secure scripting practices and mandatory code review
+- Prompt patch releases for critical issues
+
+**User Responsibilities:**
+- Keep **nvm** updated
+- Verify script downloads via PGP signatures
+- Follow secure configuration guidelines for shell environments
+
+## Legal Safe Harbor
+
+**We will NOT:**
+- Initiate legal action
+- Contact law enforcement
+- Suspend or terminate your access
+
+**You must:**
+- Only test against your own installations
+- Not access, modify, or delete user data
+- Not degrade service availability
+- Not publicly disclose before coordinated disclosure
+- Act in good faith
+
+## Recognition
+
+- **Advisory Credits**: Credit in GitHub Security Advisories (unless anonymous)
+
+## Security Updates
+
+**Stay Informed:**
+- Subscribe to GitHub releases for **nvm**
+- Enable GitHub Security Advisory notifications
+
+**Update Process:**
+- Patch releases (e.g., v0.40.3 → v0.40.4)
+- Out-of-band releases for critical issues
+- Advisories via GitHub Security Advisories
+
+## Contact Information
+
+- **Security reports**: Security tab of [nvm-sh/nvm](https://github.com/nvm-sh/nvm/security)
+- **General inquiries**: GitHub Discussions or Issues

 We meet 100% of the “passing” criteria.
 
 ### Silver
-We meet 95% of the “silver” criteria. The gaps are as follows:
-  - we do not have a DCO or a CLA process for contributions.
-  - because we only have one maintainer, the project has no way to continue if that maintainer stops being active.
-  - we do not currently document “what the user can and cannot expect in terms of security” for our project. This is planned to be completed in 2023.
+We meet 100% of the “silver” criteria.
 
 ### Gold
