Description

The gh cli is GitHub’s official command line tool. A security vulnerability has been identified in the GitHub CLI that could leak authentication tokens when cloning repositories containing git submodules hosted outside of GitHub.com and ghe.com. This vulnerability stems from several gh commands used to clone a repository with submodules from a non-GitHub host including gh repo clone, gh repo fork, and gh pr checkout. These GitHub CLI commands invoke git with instructions to retrieve authentication tokens using the credential.helper configuration variable for any host encountered. Prior to version 2.63.0, hosts other than GitHub.com and ghe.com are treated as GitHub Enterprise Server hosts and have tokens sourced from the following environment variables before falling back to host-specific tokens stored within system-specific secured storage: 1. GITHUB_ENTERPRISE_TOKEN, 2. GH_ENTERPRISE_TOKEN and 3. GITHUB_TOKEN when the CODESPACES environment variable is set. The result being git sending authentication tokens when cloning submodules. In version 2.63.0, these GitHub CLI commands will limit the hosts for which gh acts as a credential helper to source authentication tokens. Additionally, GITHUB_TOKEN will only be used for GitHub.com and ghe.com. Users are advised to upgrade. Additionally users are advised to revoke authentication tokens used with the GitHub CLI and to review their personal security log and any relevant audit logs for actions associated with their account or enterprise

Distribution advisory

This page covers CVE-2024-53858 as tracked by Debian, for the package gh. The fix is available in version 2.46.0-3; earlier versions remain affected.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is high, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability low.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: Required — someone has to click, open or visit something.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: Low — limited, and the attacker does not choose what is affected.
