CVE-2025-66031

Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Uncontrolled Recursion vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing. This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs. This issue has been patched in version 1.3.2.

Summary		(es) Forge (también llamado 'node-forge') es una implementación nativa de Transport Layer Security en JavaScript. Una vulnerabilidad de Recursión Incontrolada en las versiones 1.3.1 y anteriores de node-forge permite a atacantes remotos no autenticados crear estructuras ASN.1 profundas que desencadenan un análisis recursivo ilimitado. Esto conduce a una Denegación de Servicio (DoS) mediante el agotamiento de la pila al analizar entradas DER no confiables. Este problema ha sido parcheado en la versión 1.3.2.
