Summary

`auth.TokenForHost` violates GitHub host security boundary when sourcing authentication token within a codespace

Details

Summary

A security vulnerability has been identified in go-gh that could leak authentication tokens intended for GitHub hosts to non-GitHub hosts when within a codespace.

Details

go-gh sources authentication tokens from different environment variables depending on the host involved:

GITHUB_TOKEN, GH_TOKEN for GitHub.com and ghe.com
GITHUB_ENTERPRISE_TOKEN, GH_ENTERPRISE_TOKEN for GitHub Enterprise Server

Prior to 2.11.1, auth.TokenForHost could source a token from the GITHUB_TOKEN environment variable for a host other than GitHub.com or ghe.com when within a codespace.

In 2.11.1, auth.TokenForHost will only source a token from the GITHUB_TOKEN environment variable for GitHub.com or ghe.com hosts.

Impact

Successful exploitation could send authentication token to an unintended host.

Remediation and mitigation

Upgrade go-gh to 2.11.1
Advise extension users to regenerate authentication tokens:
- Personal access tokens
- GitHub CLI OAuth app
Advise extension users to review their personal security log and any relevant audit logs for actions associated with their account or enterprise

CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor

Summary

go-gh is a Go module for interacting with the `gh` utility and the GitHub API from the command line. A security vulnerability has been identified in `go-gh` that could leak authentication tokens intended for GitHub hosts to non-GitHub hosts when within a codespace. `go-gh` sources authentication tokens from different environment variables depending on the host involved: 1. `GITHUB_TOKEN`, `GH_TOKEN` for GitHub.com and ghe.com and 2. `GITHUB_ENTERPRISE_TOKEN`, `GH_ENTERPRISE_TOKEN` for GitHub Enterprise Server. Prior to version `2.11.1`, `auth.TokenForHost` could source a token from the `GITHUB_TOKEN` environment variable for a host other than GitHub.com or ghe.com when within a codespace. In version `2.11.1`, `auth.TokenForHost` will only source a token from the `GITHUB_TOKEN` environment variable for GitHub.com or ghe.com hosts. Successful exploitation could send authentication token to an unintended host. This issue has been addressed in version 2.11.1 and all users are advised to upgrade. Users are also advised to regenerate authentication tokens and to review their personal security log and any relevant audit logs for actions associated with their account or enterprise.
