You can always find edge cases in security. Someone somewhere is running Internet Explorer 10 but that doesn't mean Chrome fixing bugs doesn't dramatically reduce effectiveness of attacks

Describing people using Git without GitHub as an "edge case" is arrant nonsense. Git was developed for the Linux kernel, which isn't hosted on GitHub, though it has mirrors. Most corporate intranets, SourceForge, GitLab, Sourcehut, and probably most programmers' laptops have Git repositories that do not push to GitHub.

Those people won't be vulnerable to this attack, since this attack is only useful in supply chain attacks. The people vulnerable to this would be maintainers of open source repos who could end up approving a malicious PR.

Someone using git without github isn't an edge case, it's the default

[gitfan86]

Just using git isn't the vulnerability. The vulnerability is that you clone a repo that an attacker was able to put this in. 90% of the time this would happen it would be due to an attacker creating a PR on a public repo.
