CVE-2026-58043

A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix boundaries. Under `--permission`, an attacker who is granted access to one path can abuse boundary handling to read from or write to paths outside the intended filesystem allowlist. This vulnerability affects Node.js **main**, **22.x**, **24.x**, and **26.x**.

Summary		(es) Un fallo en la aplicación del Modelo de Permisos de Node.js puede otorgar en exceso acceso al sistema de archivos a través de los límites de prefijo del árbol radix. Bajo “--permission”, un atacante a quien se le concede acceso a una ruta puede abusar del manejo de límites para leer o escribir en rutas fuera de la lista de permitidos del sistema de archivos prevista. Esta vulnerabilidad afecta a Node.js main, 22.x, 24.x y 26.x.
