CVE-2025-52561

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.

Summary		(es) HTMLSanitizer.jl es un depurador de HTML basado en listas blancas. Antes de la versión 0.2.1, al añadir 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 permitía la inyección de etiquetas y la ejecución de JavaScript. Esto podía provocar cross-site scripting (XSS) en cualquier HTML depurado con esta librería. Este problema se ha corregido en la versión 0.2.1. Una solución alternativa consiste en añadir manualmente los elementos math y SVG a la lista blanca.
