Official description

Soft Serve is a self-hostable Git server for the command line. From version 0.6.0 to before version 0.11.4, an authenticated SSH user can force the server to make HTTP requests to internal/private IP addresses by running repo import with a crafted --lfs-endpoint URL. The initial batch request is blind (the response from a metadata endpoint won't parse as valid LFS JSON), but an attacker hosting a fake LFS server can chain this into full read access to internal services by returning download URLs that point at internal targets. This issue has been patched in version 0.11.4.
