CVE-2025-46835

File overwrite via Tcl argument injection

Published Jul 10, 2025 · Updated Nov 4, 2025

Argument injection in Git GUI allows context-dependent attackers to create or overwrite writable files through a crafted repository path. Git GUI passes repository-controlled path arguments beginning with Tcl redirection or pipeline metacharacters to open and exec without neutralization. Exploitation requires a user to clone an untrusted repository and edit a file in a maliciously named directory; writes are limited to files that user can modify.
