What is CVE-2023-23618?
CVE-2023-23618 is a high-severity code injection vulnerability in git-for-windows git, published on 14 Feb 2023. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
Git for Windows is the Windows port of the revision control system Git. Prior to Git for Windows version 2.39.2, when `gitk` is run on Windows, it potentially runs executables from the current directory inadvertently, which can be exploited with some social engineering to trick users into running untrusted code. A patch is available in version 2.39.2. As a workaround, avoid using `gitk` (or Git GUI's "Visualize History" functionality) in clones of untrusted repositories.
