CVE-2024-53859: go-gh `auth.TokenForHost` violates GitHub host security boundary within a codespace

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.54% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: cli go-gh 2.11.1; azl3 gh 2.62.0-1 on Azure Linux 3.0 2.62.0-1; azl3 gh 2.62.0-8 on Azure Linux 3.0 2.62.0-1.

Low priority for now. Upgrade to cli go-gh 2.11.1; azl3 gh 2.62.0-1 on Azure Linux 3.0 2.62.0-1; azl3 gh 2.62.0-8 on Azure Linux 3.0 2.62.0-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
