Nuxt: Route middleware not enforced when rendering `.server.vue` pages via `/__nuxt_island/page_*`

Nuxt is an open-source web development framework for Vue.js. In Nuxt versions 3.11.0 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6 and @nuxt/nitro-server versions 3.20.0 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6, when experimental.componentIslands is enabled (default in Nuxt 4), any .server.vue file under pages/ is automatically registered as a server island under the key page_<routeName> and exposed via the /__nuxt_island/:name endpoint. Until this fix, requests through that endpoint rendered the page component directly via the SSR renderer without instantiating Vue Router, which meant route middleware declared on the page (including definePageMeta({ middleware })) did not run. This issue has been patched in versions 3.21.6 and 4.4.6.

KHC-INVITATION-AUTOMATION Sensitive User Information Leakage in Invitation Automation

KHC-INVITATION-AUTOMATION is a GitHub automation script that automatically invites followers of a bot account to join your organization. In some commits on version 1.2, a vulnerability was identified where user data, including email addresses and Discord usernames, were exposed in API responses without proper access controls. This allowed unauthorized users to access sensitive user information by directly calling specific endpoints. This issue has been patched in a later commit on version 1.2.
