Subject: status on security of embedded repos?
Message-ID: <4e9ad5486e8a887f1e92cc4e401ca61be5f2bb9a.camel@scientia.org>

Hey.

A while ago there was this discussion about security issues with
respect to bare repos embedded in another repo[0][1].


I just wondered what's the status on this? Was that fixed in a way that
one can clone untrusted repos and navigate / use git commands within
them, without any risk… or is it still open?

Saw proposed patches like:
https://lore.kernel.org/git/pull.1261.git.git.1651861810633.gitgitgadget@gmail.com/#r

But it seems at least as of git 2.37.2, ther's no safe.barerepository
option, yet.


Also, couldn't the same happen for non-bare repos, too, or how is that
prevented for such?


Thanks,
Chris.
