v0.15.1

Compare Source

• Security: Further harden XML injection prevention during unparse (follow-up to
  v0.15.0). In addition to '<'/'>' rejection, now also reject element and
  attribute names (including @xmlns prefixes) that:
  • start with '?' or '!'
  • contain '/' or any whitespace
  • contain quotes (' or ") or '='
  • are non-strings (names must be str; no coercion)

v0.15.0

Compare Source

• Security: Prevent XML injection (CVE-2025-9375) by rejecting '<'/'>' in
  element and attribute names (including @xmlns prefixes) during unparse.
  This limits validation to avoiding tag-context escapes; attribute values
  continue to be escaped by the SAX XMLGenerator.
