+Subject: [PATCH 21/38] Block unsafe archive additions and bundle URI
+
+GHSA-539m-9xh6-q6rr reports incomplete unsafe option lists for archive inputs
+and clone bundle URLs. Caller-controlled archive additions can expose or inject
+filesystem content, while clone --bundle-uri can dereference an additional
+caller-controlled URL.
+
+Extend the existing archive denylist with --add-file and --add-virtual-file,
+and the clone denylist with --bundle-uri. Regression coverage exercises archive
+kwargs plus both clone multi-option and keyword paths.
+
+Git baseline: a23bace963d508bd96983cc637131392d3face18.
+Documentation/git-archive.adoc defines --add-file/--add-virtual-file, and
+Documentation/git-clone.adoc defines --bundle-uri as fetching from the supplied
+URI.
+
+CVE: CVE-2026-73619
+Upstream-Status: Backport [https://github.com/gitpython-developers/GitPython/commit/7a4f5dcb7bf3cbcbf6e438017efcdfe0bc0d36ca]
+
+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 7a4f5dcb7bf3cbcbf6e438017efcdfe0bc0d36ca)
