Upgrade @nuxt/nitro-server to version 4.6.2 or higher.
Overview
@nuxt/nitro-server is a Nitro server integration for Nuxt
Affected versions of this package are vulnerable to Incorrect Authorization via case-sensitive matching of server-side route rules, where route rule protections (such as redirect, headers, and proxy rules) can be bypassed by an attacker who sends a request path with differing letter case. The resolveRequestRouteRules utility fails to normalize the request path before matching it against configured route rule keys, allowing a request like /Admin to evade a rule defined for /admin. This affects any protection that relies on server-side route rule matching.
Note: This is only exploitable when server-side route rules are used to enforce access controls or apply security-relevant headers, redirects, or proxy rules, and router.options.sensitive is not explicitly set.
