Description
* ``bleach.clean`` behavior parsing embedded MathML and SVG content
with RCDATA tags did not match browser behavior and could result in
a mutation XSS.
Calls to ``bleach.clean`` with ``strip=False`` and ``math`` or
``svg`` tags and one or more of the RCDATA tags ``script``,
``noscript``, ``style``, ``noframes``, ``iframe``, ``noembed``, or
``xmp`` in the allowed tags whitelist were vulnerable to a mutation
XSS.

browser behavior.
Calls to ``bleach.clean`` allowing ``noscript`` and one or more of
the raw text tags (``title``, ``textarea``, ``script``, ``style``,
``noembed``, ``noframes``, ``iframe``, and ``xmp``) were vulnerable
to a mutation XSS.
