go-git is an extensible git implementation library written in pure Go. Prior to 5.19.1 and 6.0.0-alpha.4, go-git's SSH transport constructs the remote exec command by wrapping the repository path in single quotes without escaping single quotes embedded inside the path. A repository path containing a single quote can therefore break out of the quoted region in the exec command and be appended as additional shell tokens. This vulnerability is fixed in 5.19.1 and 6.0.0-alpha.4.

GHSA-m7cr-m3pv-hgrp — go-git: Improper single-quote escaping in go-git SSH transport

Affected: Go: github.com/go-git/go-git/v5, Go: github.com/go-git/go-git/v6, Go: github.com/go-git/go-git

### Impact

`go-git`'s SSH transport constructs the remote exec command by wrapping the repository path in single quotes without escaping single quotes embedded inside the path. This diverges from canonical Git, which shell-quotes the path through `sq_quote_buf` so that an embedded `'` becomes the `'\''` close-escape-reopen sequence and the whole path round-trips as a single quoted argument.

A repository path containing a single quote can therefore break out of the quoted region in the exec command and be appended as additional shell tokens. On SSH servers that evaluate the exec command through a shell (for example a user account whose login shell is `/bin/sh` or `/bin/bash`, or a `ForceCommand` wrapper that re-evaluates `$SSH_ORIGINAL_COMMAND`), those additional tokens execute in that account's command-execution context. SSH servers that tokenize the exec command without shell evaluation, including the canonical `git-shell` setup, are not affected.

The vulnerable behaviour is on the SSH server side, not in `go-git`: the same bytes can be produced by any SSH client. The change in `go-git` is defense-in-depth that restores parity with canonical Git's wire format and prevents `go-git` from being a vehicle for reaching shell-evaluating servers through attacker-influenced repository paths.

### Patches

Users should upgrade to a patched version in order to mitigate this issue. The fix ports `sq_quote_buf` from canonical Git into `go-git`'s SSH transport so that the wire output…
