+Subject: [PATCH 16/38] fix: reject unsafe clone templates
+
+<!-- agent -->
+
+Treat git clone --template as unsafe because caller-controlled
+templates can install hooks that execute during clone.
+
+Add regression coverage for both direct option and keyword forms.
+
+References GHSA-6p8h-3wgx-97gf.
+Validated against Git baseline a23bace9.
+
+CVE: CVE-2026-73623
+Upstream-Status: Backport [https://github.com/gitpython-developers/GitPython/commit/ffcb5359e87619f4fe4a70a4aff5f08c5580ba97]
+
+Backport Changes:
+- Omit upstream regression test changes because the current
+  PyPI source archive does not include its test suite.
+
+Co-authored-by: Sebastian Thiel <sebastian.thiel@icloud.com>
+(cherry picked from commit ffcb5359e87619f4fe4a70a4aff5f08c5580ba97)
