Incorrect handling of embedded SVG and MathML leads to mutation XSS. Affected versions did not account for namespace-related parsing differences between HTML, SVG, and MathML. Running cleanup without accounting for these differing namespaces resulted in an "impossible" DOM, which appeared "safe" when examining the DOM tree, but when serialized and deserialized, could be exploited to inject arbitrary markup
