Cross-site Scripting (XSS)

Overview mathlive is an A web component for math input Affected versions of this package are vulnerable to Cross-site Scripting XSS in the Box.toMarkup method src/core/box.ts and the MathML serializer src/formats/atom-to-math-ml.ts, which emit literal characters from LaTeX text-mode commands into...

mathlive's Lack of Escaping of HTML allows for XSS

Summary Despite the 0.104.0 patch escaping attribute-bearing constructs \htmlData, \href, text-content reflection was missed. The \text, \mbox commands accept arbitrary characters in their body and emit them raw and unescaped into both the HTML markup and the MathML output, leading to XSS. Detail...

AngleSharp HTML5 Spec Compliance: mXSS via annotation-xml HTML Integration Point Bypass

Summary The HTML specification requires that a MathML element with encoding="text/html" or encoding="application/xhtml+xml" is treated as an HTML integration point. Content inside it must be parsed as HTML, not MathML. AngleSharp does not implement this correctly. As a result, the parser produces...
