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.
bleach.clean behavior parsing noscript tags did not match
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.
This security issue was confirmed in Bleach versions v2.1.4, v3.0.2,
and v3.1.0. Earlier versions are probably affected too.
