CyberRota Analysis
AI-GeneratedThe vulnerability in lazy_html allows for cross-site scripting (XSS) attacks due to improper handling of HTML input during web page generation, specifically when parsing and serializing SVG or MathML content. Attackers can exploit this flaw to inject malicious scripts that execute in the context of the user's browser, potentially compromising user data or session integrity. Developers and organizations utilizing lazy_html versions from 0.1.0 to before 0.1.13 should prioritize patching this vulnerability to mitigate potential security risks.

Original NVD Description
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. LazyHTML.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 </style><img src=x onerror=...> inside <svg><style> 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. This issue affects lazy_html: from 0.1.0 before 0.1.13.
