CVE-2026-54753

Описание

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. This vulnerability is fixed in 22.7.2 and 23.0.0-beta.2.

A flaw was found in Nx, a monorepo solution for managing multiple projects. The local HTTP server, started by the nx graph command, incorrectly sent an Access-Control-Allow-Origin: * header in its responses. 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. In rare cases, this vulnerability could also lead to arbitrary command injection.
