This does not affect Unix systems.\n\nThis is the result of an incomplete fix for CVE-2020-27955.\n\nThis issue occurs because on Windows, [Go includes (and prefers) the current directory when the name of a command run does not contain a directory separator](https://github.com/golang/go/issues/38736).\n\n### Patches\nThis version should be patched in v2.13.2, which will be released in coordination with this security advisory.\n\n### Workarounds\nOther than avoiding untrusted repositories or using a different operating system, there is no workaround.\n\n### References\n_Are there any links users can visit to find out more?_\n\n### For more information\nIf you have any questions or comments about this advisory:\n\n- Start a discussion in [the Git LFS discussion page](https://github.com/git-lfs/git-lfs/discussions).\n- If you cannot open a discussion, please email the core team using their usernames at `github.com`.", "aliases": [ { "alias": "CVE-2021-21237"
