NVD Description
Note: Versions mentioned in the description apply only to the upstream packer package and not the packer package as distributed by Chainguard.
See How to fix? for Chainguard relevant fixed versions and status.
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.
