What is CVE-2025-27614?
CVE-2025-27614 is a high-severity command injection vulnerability in j6t gitk, 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
Gitk is a Tcl/Tk based Git history browser. Starting with 2.41.0, a Git repository can be crafted in such a way that with some social engineering a user who has cloned the repository can be tricked into running any script (e.g., Bourne shell, Perl, Python, ...) supplied by the attacker by invoking gitk filename, where filename has a particular structure. The script is run with the privileges of the user. 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.
