Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.2.1, the mistune math plugin renders inline math ($...$) and block math ($$...$$) by concatenating the raw user-supplied content directly into the HTML output without any HTML escaping. This occurs even when the parser is explicitly created with escape=True, which is supposed to guarantee that all user-controlled text is sanitised before reaching the DOM. This vulnerability is fixed in 3.2.1.

Title: Mistune de lepture, Description: Mistune es un parser de Markdown en Python con renderizadores y plugins. Antes de la 3.2.1, el plugin de matemáticas de mistune renderiza matemáticas en línea ($...$) y matemáticas en bloque ($$...$$) concatenando el contenido bruto proporcionado por el usuario directamente en la salida HTML sin ningún escape HTML. Esto ocurre incluso cuando el parser se crea explícitamente con escape=True, lo cual se supone que garantiza que todo el texto controlado por el usuario se sanitiza antes de llegar al DOM. Esta vulnerabilidad se corrige en la 3.2.1.
