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 channel in Nuxt DevTools npm package versions below 3.3.1 appears to allow arbitrary command execution on the developer's host in development environments.

What happened

The Nuxt DevTools npm package is under investigation for exposing an unauthenticated RPC channel that may allow arbitrary command execution on the developer's host. Affected versions are reportedly those below 3.3.1. To assess your exposure, check if your project includes @nuxt/devtools at a version lower than 3.3.1. It is recommended to update to version 3.3.1 and avoid running the dev server on untrusted networks. For more details, consult the primary sources linked below.
