CVE-2026-58043
Description
A flaw in the Node.js Permission Model allows attackers to bypass --permission restrictions, enabling unauthorized read or write access to files and directories.
Statement
This Important flaw in Node.js allows an attacker, when the Permission Model is enabled, to bypass intended filesystem access restrictions. An attacker with initial access to a permitted path could read from or write to unauthorized locations, leading to a privilege escalation within the application's sandboxing.
Mitigation
Avoid enabling the Node.js Permission Model by not using the `--permission` flag when starting Node.js applications. This prevents the vulnerable enforcement mechanism from being active. Disabling the Permission Model may remove an intended security layer if your application relies on it for sandboxing.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
