CVE-2023-49569

A path traversal vulnerability was discovered in go-git versions prior to
v5.11. This vulnerability allows an attacker to create and amend files
across the filesystem. In the worse case scenario, remote code execution
could be achieved. Applications are only affected if they are using the
ChrootOS https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#ChrootOS ,
which is the default when using “Plain” versions of Open and Clone funcs
(e.g. PlainClone). Applications using BoundOS
https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#BoundOS or in-memory
filesystems are not affected by this issue. This is a go-git implementation
issue and does not affect the upstream git cli.
