  "details": "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.",
