CVE-2026-54729

DSSRF is a Node.js library that provides a wide range of utilities and advanced SSRF defense checks. Prior to 1.0.5, is_url_safe can treat localhost as safe when DNS resolver 1.1.1.1 returns NXDOMAIN because dns.resolve4 yields no address and no dns.lookup fallback occurs, allowing server-side request forgery. This issue is fixed in version 1.0.5.

Summary		(es) DSSRF es una biblioteca de Node.js que proporciona una amplia gama de utilidades y comprobaciones avanzadas de defensa contra SSRF. Antes de la versión 1.0.5, is_url_safe puede tratar localhost como seguro cuando el resolvedor DNS 1.1.1.1 devuelve NXDOMAIN porque dns.resolve4 no produce ninguna dirección y no se produce una alternativa de dns.lookup, lo que permite la falsificación de petición del lado del servidor. Este problema está solucionado en la versión 1.0.5.
