CVE-2026-86418Network attack vector

Authenticated metadata disclosure via unrestricted organisation picker

Published Sep 7, 2026 · Updated Sep 8, 2026

Information disclosure in the MISP dashboard organisation picker through 2.5.45 allows remote authenticated users to read hidden organisation metadata. DashboardsController queries all organisations for the picker without appending Organisation::createConditions access-control conditions. Exploitation requires an authenticated account and Security.hide_organisation_index_from_users enabled; it reveals organisation IDs, UUIDs, and names but does not alter data.
