+Subject: [PATCH] LP#2146291: Set "resolve_entities='internal'" as default for
+ all parser subclasses.
+
+CVE: CVE-2026-41066
+Upstream-Status: Backport [https://github.com/lxml/lxml/commit/ab431ea0b9a7357d968f1d1c5c614649e9aaf358]
+
+Backport Changes:
+- Reformat the iterparse signature and resolve_entities documentation
+ without semantic changes, preserving line numbers to avoid generated
+ source-location churn.
+- Regenerate src/lxml/etree.c with Cython 3.1.4, matching the version
+ recorded in the shipped file, using
+ "python setup.py build_ext -i --with-cython".
+- Restore the shipped Cython metadata field order and omit
+ the environment-only "-w" compiler flag to avoid unrelated
+ generated changes.
+
+(cherry picked from commit ab431ea0b9a7357d968f1d1c5c614649e9aaf358)
