What is CVE-2025-46334?
CVE-2025-46334 is a high-severity command injection vulnerability in j6t git-gui, published on 10 Jul 2025. 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 GUI allows you to use the Git source control management tools via a GUI. A malicious repository can ship versions of sh.exe or typical textconv filter programs such as astextplain. Due to the unfortunate design of Tcl on Windows, the search path when looking for an executable always includes the current directory. The mentioned programs are invoked when the user selects Git Bash or Browse Files from the menu. This vulnerability is fixed in 2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1, and 2.50.1.
Weakness: CWE-78
