CVE-2026-73625Public exploitNetwork attack vector

Remote code execution via kwarg value smuggling

Published Aug 13, 2026 · Updated Aug 13, 2026

Command injection in GitPython before 3.1.54 allows remote authenticated users to execute arbitrary OS commands through crafted option dictionaries. The check_unsafe_options guard inspects only kwarg keys, while transform_kwarg splits a single-character value into a second Git option token that bypasses the denylist. An embedding application must forward an attacker-controlled option dictionary; the smuggled --upload-pack option runs commands with the host process's privileges.
