+Subject: [PATCH] fix(create): reject ambiguous venv paths (#3426)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+CVE: CVE-2026-113715
+Upstream-Status: Backport [https://github.com/pypa/virtualenv/commit/b0008a58885ded9227faf8f910c6c402712c750a]
+
+Backport Changes:
+- Reuse the identical _one_line helper already backported for
+  CVE-2026-102938 because 21.2.1 lacks the later
+  virtualenv.util.text.collapse_line_boundaries helper.
+- Use the 21.2.1 system_executable API and GraalVM implementation name
+  in the launcher settings and regression test instead of the later
+  system_exe API and GraalPy name.
+- Import Final in the older test module for the upstream annotations.
+- Omit the upstream release changelog fragment.
