AI-suggested
Upgrade Nuxt UI to version 4.8.1 or later, where the issue is fixed by including the method and action attributes in server-rendered forms to prevent default GET submissions. No other mitigation is required as the fix addresses the root cause.
Description
CVE-2026-123808 is a vulnerability in Nuxt UI versions prior to 4.8.1 where server-rendered forms omit method and action attributes, relying on client-side Vue hydration to prevent native form submission. If a user submits a form before hydration completes or if the client bundle is blocked, sensitive credential data can be exposed in the URL query string, potentially leaking to browser history, logs, and Referer headers. This issue is fixed in version 4.8.1.
