CVE-2026-40465Network attack vector

User redirection via unvalidated redirect parameter

Published Aug 31, 2026 · Updated Aug 31, 2026

Open redirect in Nokia NSP 23.11, 24.4, 24.8, 24.11, 25.4, 25.8, and 25.11 allows remote attackers to redirect users via a crafted URL. The server accepts a URL or redirect parameter without sufficient server-side validation and issues a redirect to an untrusted destination. Exploitation requires a user to follow an attacker-controlled link; the reported consequence is navigation to an untrusted site.
