Summary
Nx is a monorepo solution for TypeScript and polyglot codebases.
From 17.0.4 until 22.7.2 and 23.0.0-beta.2, the local HTTP server started by nx graph sent Access-Control-Allow-Origin: * on every response, letting any website a developer visited read the server's responses cross-origin — including the full project graph and the output of the /help endpoint, which runs a target's configured help command.
The practical impact is typically cross-origin information disclosure, but can be arbitrary command injection in rare cases. A flaw was found in Nx, a monorepo solution for managing multiple projects.
This misconfiguration allows a remote attacker to read sensitive project information, such as the full project graph, from a developer's system when they visit a malicious website. Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:L/A:N).
Weakness: CWE-346. Affected Red Hat products: Red Hat Ansible Automation Platform 2; Red Hat Enterprise Linux 10.
