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.

CVSS score applicability

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

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.
