        "text": "CVE-2026-2297: CPython's SourcelessFileLoader read legacy .pyc files with a\n  plain _io.FileIO instead of io.open_code(), because FileLoader.get_data()\n  only routed SourceLoader and ExtensionFileLoader subclasses through\n  open_code(). A PEP 578 open_code hook installed to vet code before it is\n  executed was therefore not consulted when a sourceless .pyc was imported,\n  letting code loaded that way escape such validation (CWE-668). Backport of\n  cpython a51b1b51 (gh-145506): SourcelessFileLoader is added to the\n  open_code() branch of FileLoader.get_data(). As in the upstream 3.10\n  backport 876858c9, the frozen Python/importlib_external.h is regenerated\n  as well - the interpreter executes the frozen blob, not the .py file.\n- CVE-2026-6879: xml.etree.ElementTree.Element.findall(), a fully consumed\n  Element.iterfind(), and Element.find() when the first match sits near the\n  end of the sibling list had O(n**2) time complexity for XPath index\n  predicates ([1], [last()], [last()-N]), because the predicate re-ran\n  parent.findall(tag) for every candidate sibling. Parsing an attacker-supplied\n  XML document with many same-tag siblings could therefore consume excessive\n  CPU time (CWE-407, inefficient algorithmic complexity). Backport of cpython\n  2ffab083 (gh-152674): the (parent, tag) lookup is cached so each sibling\n  group is scanned once.",
