How to Fix CVE-2025-24360
To remediate this vulnerability, upgrade all affected @nuxt/vite builder dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install @nuxt/vite-builder@3.15.3Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @nuxt/vite-builderHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2025-24360, inspect your project dependencies using npm:
npm ls @nuxt/vite-builderAnalyze the terminal output to locate any version of @nuxt/vite builder in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.15.3), your application is affected.
Note: The npm ls @nuxt/vite-builder command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

"details" : "### Summary\nNuxt allows any websites to send any requests to the development server and read the response due to default CORS settings.\n\n### Details\nWhile Vite patched the default CORS settings to fix https://github.com/vitejs/vite/security/advisories/GHSA-vg6x-rcgg-rjx6, nuxt uses its own CORS handler by default (https://github.com/nuxt/nuxt/pull/23995).\n\nhttps://github.com/nuxt/nuxt/blob/7d345c71462d90187fd09c96c7692f306c90def5/packages/vite/src/client.ts#L257-L263\n\nThat CORS handler sets `Access-Control-Allow-Origin: *`.\n\n> [!IMPORTANT] \n> If on an affected version, it may be possible to opt-out of the default Nuxt CORS handler by configuring `vite.server.cors`.\n\n### PoC\n1. Start a dev server in any nuxt project using Vite by `nuxt dev`.\n2. Send a fetch request to `http://localhost:3000/_nuxt/app.vue` (`fetch('http://localhost:3000/_nuxt/app.vue')`) from a different origin page.\n\n### Impact\nUsers with the default server.cors option using Vite builder may get the source code stolen by malicious websites\n\n### Additional Information\n`/__nuxt_vite_node__/manifest` / `/__nuxt_vite_node__/module` also seems to have `Access-Control-Allow-Origin: *`, so it maybe also possible to exploit that handler.\nhttps://github.com/nuxt/nuxt/blob/7d345c71462d90187fd09c96c7692f306c90def5/packages/vite/src/vite-node.ts#L39\nAlthough I didn't find a valid module id.\nNote that this handler is probably also vulnerable to DNS rebinding attacks as I didn't find any host header checks.",
