From 3.11.0 until 3.21.4 and 4.4.4, Nuxt compares route-rule keys with the raw request path while route resolution decodes dynamic and catch-all parameters, allowing a percent-encoded segment to resolve to a protected page without matching the routeRules entry intended for that path. As a result, appMiddleware can be skipped during server rendering and an unauthenticated requester can receive the gated page and its SSR data. The same mismatch affects app-manifest rules including redirect, appLayout, ssr, prerender, and payload flags derived from cache, isr, and swr. This vulnerability is fixed in 4.4.4 and 3.21.4."
