Current Description
Mistune is a Python Markdown parser with renderers and plugins. In 3.2.0 and earlier, in src/mistune/directives/image.py, the render_figure() function concatenates figclass and figwidth options directly into HTML attributes without escaping. This allows attribute injection and XSS even when HTMLRenderer(escape=True) is used, because these values bypass the inline renderer. Version 3.2.1 contains a patch.

Title: Mistune de lepture, Description: Mistune es un analizador de Markdown de Python con renderizadores y complementos. En 3.2.0 y versiones anteriores, en src/mistune/directives/image.py, la función render_figure() concatena las opciones figclass y figwidth directamente en atributos HTML sin escapar. Esto permite la inyección de atributos y XSS incluso cuando se utiliza HTMLRenderer(escape=True), porque estos valores eluden el renderizador en línea.
