How to fix?

Upgrade Alpine:3.24 py3-gitpython to version 3.1.61-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-gitpython package and not the py3-gitpython package as distributed by Alpine. See How to fix? for Alpine:3.24 relevant fixed versions and status.

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.
