Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: async-git versions prior to 1.13.2

Description: The issue allows OS Command Injection via shell metacharacters, as demonstrated by git.reset and git.tag. This may lead to remote code execution if a client of the library calls the vulnerable method with untrusted input.

Recommendations: For versions prior to 1.13.2, update async-git to version 1.13.2 to resolve the issue. As a temporary workaround, consider sanitizing untrusted user input before passing it to one of the vulnerable functions, such as git.reset and git.tag.
