From @nuxt/webpack-builder 3.0.0 and @nuxt/rspack-builder 3.12.2 until 4.6.4, the development middleware trusts Origin, Referer, or Sec-Fetch-Site when the Host header names the same attacker-controlled hostname. After DNS rebinding changes that hostname to a loopback address, a malicious page opened by a developer can read /_nuxt/*.js client chunks and inline source maps, exposing compiled application source, local filesystem paths, and developer-controlled values embedded in the client bundle. The attacker must know or guess the development-server port and induce the developer to open the malicious page; Chrome 142 and later and other Chromium-based browsers that enforce Local Network Access restrictions prompt before a public page can reach the loopback address. The default Vite builder and production builds are unaffected. This issue is fixed in version 4.6.4."}], "source": {"advisory": "GHSA-x2wv-5868-p7v2", "discovery": "UNKNOWN"}}}}
