GHSA-mm7x-qfjj-5g2c Ammonia incorrectly handles embedded SVG and MathML leading to mutation XSS after removal

• crates.io ammonia: >= 4.1.0, < 4.1.2 → fixed in 4.1.2 • crates.io ammonia: >= 4.0.0, < 4.0.1 → fixed in 4.0.1 • crates.io ammonia: < 3.3.1 → fixed in 3.3.1

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.
