CVE-2026-128074

Nuxt is an open-source web development framework for Vue.js. From 4.6.0 until 4.6.4, payload.json URL generation and the experimental early-404 path use a trailing-slash regular expression whose work grows quadratically with a long run of slash characters. An unauthenticated request can synchronously occupy the Node.js event loop and delay other requests when server-side rendering uses isr, swr, or cache route rules, or when experimental.early404 is enabled. Applications without those route rules and without experimental.early404, fully prerendered applications, and client-only applications are unaffected; the impact is limited to availability. This issue is fixed in version 4.6.4.
