Git LFS can execute a Git binary from the current directory
On Windows, if Git LFS operates on a malicious repository with a
git.exe file in the current directory, that program would be executed, permitting the attacker to execute arbitrary code. This does not affect Unix systems.
This occurs because on Windows, Go includes (and prefers) the current directory when the name of a command run does not contain a directory separator.
This version should be patched in v2.12.1, which will be released in coordination with this security advisory.
Other than avoiding untrusted repositories, there is no workaround.
