Summary
The GitHub CLI is GitHub’s official command line tool. A security vulnerability has been identified in GitHub CLI that could create or overwrite files in unintended directories when users download a malicious GitHub Actions workflow artifact through gh run download. This vulnerability stems from a GitHub Actions workflow artifact named .. when downloaded using gh run download. The artifact name and --dir flag are used to determine the artifact’s download path.
