Package : python-bleach
CVE ID : CVE-2020-6816

It was reported that python-bleach, a whitelist-based HTML-sanitizing
library, is prone to a mutation XSS vulnerability in bleach.clean when
strip=False and 'math' or 'svg' tags and one or more of the RCDATA tags
were whitelisted.
For the stable distribution (buster), this problem has been fixed in
version 3.1.2-0+deb10u1.
