CVE-2026-72924

GitHub CLI (gh) is GitHub's official command line tool. Versions 2.28.0 through 2.97.0 bind the local listener created by gh codespace ports forward to all available network interfaces by default. While port forwarding is active, a service in a Codespace can therefore become reachable through the user's non-loopback local IP addresses by other hosts that can route to the user's machine. This behavior does not change the GitHub-side visibility of the Codespaces port. Instead, it exposes the forwarded service through a wildcard-bound listener on the user's local machine, even when the source Codespaces port remains private. Exploitation requires a network-adjacent attacker to reach the victim's machine while forwarding is active. This issue is fixed in version 2.98.0.

These are all security issues fixed in the gh-2.102.0-1.1 package on the GA media of openSUSE Tumbleweed.

This update for gh fixes the following issues:

Changes in gh:

• Update to version 2.102.0, fixing four security issues (GHSA-39wj-f2f4-978v, GHSA-4mq3-hpgx-9cx8, GHSA-qcwj-mr2r-2cx7, GHSA-wjmr-j3rp-mh2g):

  • gh release/run/attestation download and repo read-file --output could write to an unintended file through symbolic links
  • gh attestation verify compared --source-ref case-insensitively
  • gh attestation verify matched --signer-workflow only by prefix
  • gh skill search could inject options into gh skill install
  • Copy auth codes to the clipboard by default (gh config set clipboard disabled to opt out)
  • Remove the gh repo garden command and the multi-account migration
  • Use API SSH URLs for repository clones
  • Validate repository names during interactive creation
  • Fix remote branch deletion on owner case mismatch
  • Propagate the gh path to extensions
  • Allow ghu_ tokens to attach files
  • Allow gh repo set-default --unset without an argument
  • Bump go-gh to 2.16.1, golang.org/x/crypto to 0.57.0, github.com/klauspost/compress to 1.20.1 and Go to 1.27.1

• Update golang.org/x/net to 0.60.0 to fix excessive CPU consumption on repeated HTTP/2 initial window changes (CVE-2026-78669, bsc#1285291).

• Require golang(API) >= 1.27 as upstream moved to Go 1.27.
