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.
This security issue was confirmed in Bleach version v3.1.1. Earlier
versions are likely affected too.
Anyone using Bleach <=v3.1.1 is encouraged to upgrade.
