NewCVE-2026-71316 (opens in a new tab)How to fix?
Upgrade @nuxt/nitro-server to version 4.5.1 or higher.
Overview
@nuxt/nitro-server is a Nitro server integration for Nuxt
Affected versions of this package are vulnerable to Missing Authorization via the cache:nuxt:payload. An attacker can access sensitive server-side rendered data belonging to other users by making a request to the /_payload.json endpoint after a protected, cached page has been accessed by an authenticated user. This can result in disclosure of personal information such as profile, tenant, billing, or token-like values to unauthorized or unauthenticated clients.
Workaround
This vulnerability can be mitigated by setting experimental.payloadExtraction: false, avoiding the use of cache / swr / isr on authenticated pages, or requiring authentication for /**/_payload.json at a proxy or CDN.
