CVE-2026-86418 — MISP Dashboard Organisation Picker Exposes Hidden Organisation Metadata to Unauthorized Users
Affected versions of MISP expose organisation metadata through the dashboard organisation picker without applying the same visibility restrictions enforced by the normal organisation index and per-organisation view. The affected endpoint returned fields including: * organisation ID; * UUID; * name. When Security.hide_organisation_index_from_users was enabled, normal organisation enumeration was restricted, but the dashboard picker still queried all organisations. This allowed authenticated users to discover organisations that should have remained hidden from them. The fix calls Organisation::createConditions($this->Auth->user()) and appends the resulting ACL conditions to the picker query. Ordinary users are thereby limited to organisations associated with events or proposals they can already see, plus their own organisation, while users with the appropriate sharing-group privilege…
