nodejs: Node.js: Local server can be started without network permission via Permission API flaw

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...

Canonical Livepatch 安全漏洞

Canonical Livepatch is a system component developed by Canonical OpenSource that manages kernel hotfix updates and patches. Versions of Canonical Livepatch prior to 10.15.0 contained security vulnerabilities. These vulnerabilities were caused by improper access control, allowing local...

Node.js: Node.js: Unauthorized inter-process communication due to missing Unix Domain Socket permission checks

A flaw was found in Node.js. The Node.js Permission Model, designed to restrict network access, incorrectly omits permission checks for Unix Domain Socket UDS server operations. This allows local code, even when explicitly denied network access, to create and expose inter-process communication IP...

nodejs: Nodejs network segmentation bypass

A flaw in Node.js's permission model allows Unix Domain Socket UDS connections to bypass network restrictions when --permission is enabled. Even without --allow-net, attacker-controlled inputs such as URLs or socketPath options can connect to arbitrary local sockets via net, tls, or undici/fetch...

BIT-NODE-2026-21711

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 IP...
