Summary

Incorrect handling of embedded SVG and MathML leads to mutation XSS after removal

Details

Affected versions of this crate did not correctly strip namespace-incompatible tags in certain situations, causing it to incorrectly account for differences between HTML, SVG, and MathML.

This vulnerability only has an effect when the svg or math tag is allowed, because it relies on a tag being parsed as html during the cleaning process, but serialized in a way that causes in to be parsed as xml by the browser.

Additionally, the application using this library must allow a tag that is parsed as raw text in HTML. These [elements] are:

title
textarea
xmp
iframe
noembed
noframes
plaintext
noscript
style
script

Applications that do not explicitly allow any of these tags should not be affected, since none are allowed by default.
