Upgrade nuxt to version 4.6.3 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Authorization via dot segment handling in toRequestEvent in packages/nitro-server/src/runtime/utils/event.ts. An attacker can send a request containing . or .. path segments (including their percent-encoded forms such as %2e) to cause the server-side router to resolve the path to a different route than the one named by event.path, potentially bypassing server middleware path checks and accessing unintended pages or resources.
Note: Path checks in server middleware should also account for the page router matching paths case-insensitively unless router.options.sensitive is set.
