Summary

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-284h-m62q-gf8w. This link is maintained to preserve external references. ## Original 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.

Affected packages

Remediation: No patched version is listed by GitHub.
