Recommendation
It is recommended to update Nuxt to versions 4.4.7 or 3.21.7 to mitigate this vulnerability and implement additional validation mechanisms for redirects.
Original NVD description (English source)
Nuxt versions 4.0.0 before 4.4.7 and 3.x before 3.21.7 contain a server-side open redirect vulnerability in navigateTo that fails to properly validate path-normalized payloads like /..//evil.com and /.//evil.com. Attackers can bypass external-host checks using path-normalization techniques to redirect users to attacker-controlled sites via the Location header or meta-refresh, enabling phishing and OAuth authorization-code theft.
