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.

The version of gh installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-53859 advisory.

(CVE-2024-53859)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 24.04 LTS / 24.10 host has a package installed that is affected by a vulnerability as referenced in the USN-7362-1 advisory.

    It was discovered that go-gh incorrectly handled authentication tokens. An attacker could possibly use     this issue to leak

    authentication tokens to the wrong host. (CVE-2024-53859)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
