Prior to 4.12.16, Improper handling of JSX element tag names in hono/jsx allowed unvalidated tag names to be directly inserted into the generated HTML output. When untrusted input is used as a tag name via the programmatic jsx() or createElement() APIs during server-side rendering, specially crafted values may break out of the intended element context and inject unintended HTML. This vulnerability is fixed in 4.12.16."},{"lang":"es","value":"Hono es un framework de aplicación web que proporciona soporte para cualquier entorno de ejecución de JavaScript. Antes de la versión 4.12.16, el manejo inadecuado de los nombres de etiquetas de elementos JSX en hono/jsx permitía que nombres de etiquetas no validados fueran insertados directamente en la salida HTML generada. Cuando una entrada no confiable se utiliza como nombre de etiqueta a través de las API programáticas jsx() o createElement() durante la renderización del lado del servidor, valores especialmente diseñados pueden escapar del contexto del elemento previsto e inyectar HTML no deseado.
