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.

We recommend that you upgrade your python-bleach packages.
