Name of the Vulnerable Software and Affected Versions git-fastclone versions prior to 1.0.5

Description The issue allows an attacker to execute malicious commands by modifying user modifiable strings that are passed as arguments to cd and git clone commands in the library. This is due to the library passing these strings directly to a shell command.

Recommendations For git-fastclone versions prior to 1.0.5, update to version 1.0.5 or later to resolve the issue. As a temporary workaround, consider restricting the use of user modifiable strings in the cd and git clone commands to minimize the risk of exploitation.
