Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2021-02-02 08:38:11 UTC 
A mutation XSS affects users calling bleach.clean with all of:

- svg or math in the allowed tags
- p or br in allowed tags
- style in allowed tags
- the keyword argument strip_comments=False

Note: none of the above tags are in the default allowed tags and strip_comments defaults to True.
