Medium (6.5). Fixed in @nuxt/nitro-server 4.6.4.
On this page
Nuxt is an open-source web development framework for Vue.js. From 4.6.0 until 4.6.4, Nuxt parses a request path beginning with // as a URL host before rendering a page, while Nitro server/middleware and routeRules continue to evaluate the original path. An unauthenticated request such as //x/admin can therefore resolve to the /admin page without route-scoped serverHandlers, server/middleware path checks, redirects, or security headers configured for /admin. API handlers in server/api and server/routes, appMiddleware, page middleware are unaffected. This issue is fixed in version 4.6.4.

Explain CVE-2026-128077 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-128077?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-128077?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-128077 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
