+Subject: [PATCH] fix: validate config section delimiters
+
+GHSA-3rp5-jjmw-4wv2 identified that configuration section names could alter the
+structure of serialized config despite the existing control-character checks.
+
+Reject unquoted closing section delimiters across all writer entry points
+while preserving valid delimiters inside quoted subsections and the
+existing option-name behavior. Add regression coverage for unsafe plain and
+quoted-subsection-shaped names as well as a valid quoted subsection.
+
+Git baseline: a23bace963d508bd96983cc637131392d3face18. Git config parsing
+treats an unquoted closing bracket as the end of a basic section header, while
+its extended form permits brackets inside a quoted subsection and requires a
+final bracket after the closing quote.
+
+CVE: CVE-2026-69097
+Upstream-Status: Backport [https://github.com/gitpython-developers/GitPython/commit/1ed1b924f4e2d2ee7bab296df77b978af21853f1]
+
+Backport Changes:
+- Omitted test/test_config.py because the current PyPI
+  source archive does not include the test suite and
+  the python3-git recipe does not run it.
+
+Co-authored-by: Sebastian Thiel <sebastian.thiel@icloud.com>
