Summary
HTMLSanitizer.jl is a Whitelist-based HTML sanitizer. Prior to version 0.2.1, when adding the style tag to the whitelist, content inside the tag is incorrectly unescaped, and closing tags injected as content are interpreted as real HTML, enabling tag injection and JavaScript execution. This could result in possible cross-site scripting (XSS) in any HTML that is sanitized with this library. This issue has been patched in version 0.2.1. A workaround involves adding the math and svg elements to the whitelist manually.

Antes de la versi\u00f3n 0.2.1, al a\u00f1adir la etiqueta de estilo a la lista blanca, el contenido dentro de la etiqueta se eliminaba incorrectamente del escape, y las etiquetas de cierre inyectadas como contenido se interpretaban como HTML real, lo que permit\u00eda la inyecci\u00f3n de etiquetas y la ejecuci\u00f3n de JavaScript. Esto pod\u00eda provocar cross-site scripting (XSS) en cualquier HTML depurado con esta librer\u00eda. Este problema se ha corregido en la versi\u00f3n 0.2.1. Una soluci\u00f3n alternativa consiste en a\u00f1adir manualmente los elementos math y SVG a la lista blanca."
