Detailed vulnerability description
The vulnerability allows a remote user to execute arbitrary os commands.
The vulnerability exists due to improper neutralization of argument delimiters in a command in the check_unsafe_options guard and single-character kwarg transformation logic when processing user-supplied keyword arguments for guarded git methods. A remote user can supply a single-character kwarg value that is transformed into a separate unsafe git option token to execute arbitrary os commands.
In the default configuration, the issue affects guarded methods including clone, fetch, pull, push, ls_remote, iter_commits, blame, and archive.
