Improper access control in Node.js - CVE-2026-56847

Vulnerability identifier: #VU140046

CSH Severity: Low

CVSS v4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-56847

CWE-ID: CWE-284

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to write trace logs outside allowed filesystem paths.

The vulnerability exists due to improper access control in Node.js Permission Model enforcement when trace_events.createTracing().enable() writes trace logs. A local user can invoke trace_events.createTracing().enable() to write trace logs outside allowed filesystem paths.

This issue affects configurations that use the Permission Model with --allow-fs-write restrictions.
