CVE-2026-40463Network attack vector

Authenticated restricted-page access via missing URL authorization

Published Aug 31, 2026 · Updated Aug 31, 2026

Improper access control in Nokia WaveSuite 23.6, 23.12, 24.6, 24.12, and 25.6 allows remote authenticated users to open restricted pages. The CPB Log Files request path serves higher-role pages after a direct browser URL request without enforcing the caller’s required role. Exploitation requires a valid low-privilege account; Nokia has not disclosed which page contents or actions become available.
