CVE-2026-56326: Nuxt

Medium severity, CVSS 6.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Nuxt Nuxt: from 3.0.0, before 3.21.7 (fixed in 3.21.7); from 4.0.0, before 4.4.7 (fixed in 4.4.7)
