CVE-2026-54705

MathLive provides web components for math display and input. Prior to 0.110.0, MathLive fails to escape text-mode content in \text{} and \mbox{} commands in Box.toMarkup at src/core/box.ts, in xmlEscape, scanText, and text-mode output in src/formats/atom-to-math-ml.ts, and through convertLatexToMarkup, convertLatexToMathMl, <math-span>, <math-div>, and the default identity MathfieldElement.createHTML, allowing malicious input to run arbitrary JavaScript when rendered. This issue is fixed in version 0.110.0.

Summary		(es) MathLive proporciona componentes web para la visualización e introducción de matemáticas. Antes de 0.110.0, MathLive falla al escapar el contenido en modo texto en los comandos \text{} y \mbox{} en Box.toMarkup en src/core/box.ts, en xmlEscape, scanText, y la salida en modo texto en src/formats/atom-to-math-ml.ts, y a través de convertLatexToMarkup, convertLatexToMathMl, [math-span], [math-div], y la identidad predeterminada MathfieldElement.createHTML, permitiendo que una entrada maliciosa ejecute JavaScript arbitrario cuando se renderiza. Este problema está solucionado en la versión 0.110.0.
