FKIE_CVE-2026-56326
Vulnerability from fkie_nvd - Published: 2026-06-22 22:16 - Updated: 2026-06-25 16:51
Severity
Summary
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.
