CVE-2026-56847
Description
A flaw in the Node.js Permission Model allows trace_events.createTracing().enable() to bypass --allow-fs-write restrictions and write trace logs outside intended paths, potentially leading to unauthorized information disclosure.
Statement
This Low impact flaw in Node.js allows a local attacker to bypass filesystem write restrictions for trace logs when using trace_events.createTracing().enable(). This limited integrity impact permits specific log files to be written outside the intended --allow-fs-write boundary.
Mitigation
Avoid using the trace_events.createTracing().enable() function in environments that rely on the Node.js Permission Model for file system isolation. Be aware that avoiding this function disables dynamic trace log generation, which may impact performance profiling, APM monitoring, and diagnostic workflows.
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).
