NewCVE-2026-106071 (opens in a new tab)How to fix?
Upgrade node to version 26.12.1 or higher.
Overview
node is a JavaScript runtime built on Chrome's V8 JavaScript engine.
Affected versions of this package are vulnerable to Incorrect Authorization via the prefix-matching loop in the FSPermission filesystem permission tree. An attacker can make an application running with the Permission Model read or write paths outside its configured wildcard grant by supplying a path that shares the grant’s prefix but diverges afterward; for example, /tmp/test2 can be accepted under --allow-fs-write=/tmp/test/*. This exposes or modifies files the operator intended to deny.
