CVE-2026-123808

Nuxt UI is an intuitive Vue UI library powered by Reka UI and Tailwind CSS. Prior to 4.8.1, the server-rendered form element produced by UForm in src/runtime/components/Form.vue omits the method and action attributes and relies solely on the hydrated @submit.prevent handler to stop native submission. UAuthForm composes UForm and can render named credential fields, including an input with type password, inside the same markup. If a user submits before Vue hydration completes, or when the client bundle is blocked or unavailable, the browser performs its default GET submission and serializes the named fields into the current URL query string. The credentials can then appear in the address bar, browser history, reverse-proxy, CDN, or WAF request logs, and Referer headers sent with same-origin subresource requests. This issue is fixed in version 4.8.1.
