Nuxt DevTools npm Package: Unauthenticated RPC Vulnerability

EARLY WARNING · UNCONFIRMED. This page describes a developing threat that 0Day surfaced from early signals and has not yet independently confirmed. Details may change. Always verify against the primary sources before acting.

GHSA-279X-MWFV-VCQVSeverity: HIGH

An unauthenticated RPC vulnerability in Nuxt DevTools npm package versions <3.3.1 appears to allow arbitrary command execution on the developer's host.

What happened

An early warning has been issued regarding a critical vulnerability in the Nuxt DevTools npm package. Versions prior to 3.3.1 reportedly expose an unauthenticated RPC channel that enables arbitrary command execution on the developer's host when running in development mode. This vulnerability allows any client to call RPC methods without authentication, potentially enabling attackers to execute arbitrary commands. To assess exposure, developers should check if they are using an affected version of @nuxt/devtools. It is recommended to update to version 3.3.1 and avoid running the dev server on untrusted networks with the --host option. For more details, consult the primary sources.
