El endpoint solo valida que la URL solicitada inicialmente se resuelva a una IP pública, luego recupera el HTML de la página del lado del servidor y lo entrega, sin sanitizar, a un subproceso de WeasyPrint. Las referencias a recursos incrustados en el HTML recuperado (por ejemplo, “menor queimg src=“http://169.254.169.254/...”mayor que”) son recuperadas por WeasyPrint sin filtrado SSRF por recurso, permitiendo que una página controlada por el atacante haga que el servidor recupere endpoints de metadatos en la nube o recursos de red internos y filtre su contenido de vuelta al PDF generado."
