If you discover a security vulnerability within this repository, we encourage responsible disclosure. Please report any security issues to help us keep Ubuntu on WSL secure for everyone.

The most straightforward way to report a security vulnerability is via GitHub. For detailed instructions, please review the Privately reporting a security vulnerability documentation. This method enables you to communicate vulnerabilities directly and confidentially with the Ubuntu on WSL maintainers.

The project's admins will be notified of the issue and will work with you to determine whether the issue qualifies as a security issue and, if so, in which component. We will then handle finding a fix, getting a CVE assigned and coordinating the release of the fix to the various Linux distributions.

The Ubuntu Security disclosure and embargo policy contains more information about what you can expect when you contact us, and what we expect from you.

1. Go to the Security Advisories Page of the Ubuntu WSL repository.
2. Click "Report a Vulnerability."
3. Provide detailed information about the vulnerability, including steps to reproduce, affected versions, and potential impact.
