How to fix?

Upgrade Minimos:latest nodejs-25 to version 25.8.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs-25 package and not the nodejs-25 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

A flaw in Node.js Permission Model network enforcement leaves Unix Domain Socket (UDS) server operations without the required permission checks, while all comparable network paths correctly enforce them.

As a result, code running under --permission without --allow-net can create and expose local IPC endpoints, allowing communication with other processes on the same host outside of the intended network restriction boundary.

This vulnerability affects Node.js 25.x processes using the Permission Model where --allow-net is intentionally omitted to restrict network access. Note that --allow-net is currently an experimental feature.
