GitPython before 3.1.59 Remote Code Execution via Config Injection

Published Aug 25, 2026 · Updated Oct 8, 2026 · Assigned by VulnCheck

Description

GitPython before 3.1.59 fails to safely re-serialize multi-line git-config values during write operations, corrupting dormant quoted values into injected directives like core.hooksPath. Attackers can craft config files with embedded newlines that become live git directives after any unrelated GitPython config write, enabling arbitrary code execution via hook invocation.
