Summary		(es) Twig es un lenguaje de plantillas para PHP. Antes de la versión 3.26.0, el filtro spaceless obsoleto está registrado como seguro para HTML, lo que provoca que el autoescape de Twig emita marcado controlado por el atacante sin escapar cuando spaceless se aplica a una entrada no confiable. Este problema está solucionado en la versión 3.26.0.
