I guess this is only specific to a file in the root of the repo, so it doesn't allow for an NPM supply chain attack?

It has nothing to do with npm. However, a binary could be configured to extract your git/npm secrets using this exploit, which could then lead to a npm supply chain attack (or pip, etc. etc.).

I meant the attack would be the other way around- if an infected package had the git.exe file in their root.

Or, the infected package could also copy that file into the parent project's root.

		Oh yeah that's a good point - two layers of auto executing scripts/binaries.
