  "details": "Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in dashbitco lazy_html allows mutation XSS via a parse and serialize round-trip of attacker-supplied HTML.\n\nLazyHTML.to_html/2 and LazyHTML.Tree.to_html/2 decide whether to escape an element's text from its tag name alone. A style or script element inside SVG or MathML foreign content is parsed with character references decoded, but is serialized as an HTML raw-text element, so its text is emitted unescaped. Encoded markup such as \u0026lt;/style\u0026gt;\u0026lt;img src=x onerror=...\u0026gt; inside \u003csvg\u003e\u003cstyle\u003e therefore closes the element on re-parse and becomes live markup. Applications that parse untrusted HTML with lazy_html, filter the document or tree, and serialize it for display are affected, since the payload is a plain text node that no element or attribute filter sees.\n\nThis issue affects lazy_html: from 0.1.0 before 0.1.13.",
