Nuxt - Server-Side Open Redirect via Path-Normalization Bypass in navigateTo

Assigner: VulnCheck
Reserved: 20.06.2026 Published: 22.06.2026 Updated: 23.06.2026

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.
