A flaw in Node.js Permission API can cause a local server to be started (via a Unix domain socket), even without the `--allow-net` permission. This vulnerability affects one supported release line: **Node.js 26**.

A flaw was found in Node.js. The Node.js Permission API can allow a local server to be started through a Unix domain socket, even when the `--allow-net` permission is not explicitly granted. This bypasses intended security restrictions, potentially leading to unintended local network exposure or integrity impact.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
