3.15.3 is the next regularly scheduled patch release.

👀 Highlights

CORS configuration for dev server

Alongside a range of improvements, we've also shipped a significant fix to impose CORS origin restrictions on the dev server. This applies to your Vite or Webpack/Rspack dev middleware only.

This is a significant/breaking change we would not normally ship in a patch but it is a security fix (see https://github.com/nuxt/nuxt/security/advisories/GHSA-4gf7-ff8x-hq99 and https://github.com/nuxt/nuxt/security/advisories/GHSA-2452-6xj8-jh47) and we urge you to update ASAP.

You can configure the allowed origins and other CORS options via the devServer.cors options in your nuxt.config, which may be relevant if you are developing with a custom hostname:

export default defineNuxtConfig({
  devServer: {
    cors: {
      origin: ['https://custom-origin.com'],
    },
  },
})
