CVE ID :CVE-2026-56422<\/p>\n
Published : June 22, 2026, 11:43 a.m. | 2\u00a0hours ago<\/p>\n
Description :Multiple MISP core controllers and model capture paths accepted client-controlled request fields such as primary keys (id) and ownership\/scope foreign keys (event_id, org_id, user_id, sharing_group_id, galaxy_cluster_uuid, organisation_uuid, and related nested object identifiers) without consistently stripping, pinning, or revalidating them against the server-authorized object.<\/p>\n
In affected paths, an authenticated user with access to one authorized object could submit crafted REST or form payloads that caused MISP to save data against a different object than the one checked by the authorization logic. Depending on the endpoint, this could allow object overwrite, object re-parenting, ownership transfer, unauthorized sharing-group scoping, event\/object injection, proposal retargeting, or stored attacker-controlled content appearing in another user\u2019s context.<\/p>\n
The fixes harden affected create\/edit\/import flows by stripping client-supplied primary keys on create-only saves, re-pinning route- or database-authorized identifiers before save operations, validating effective sharing-group scope, and adding field whitelists where ownership fields must never be editable. The initial broad fix also added a central CRUDComponent::edit()\u00a0primary-key re-pin so payload-supplied IDs cannot redirect saves away from the already-authorized row. GitHub\u2019s patch for 7acf8220c\u00a0describes this central issue as CRUDComponent::edit()\u00a0copying supplied fields, including a payload primary key, onto the loaded record, allowing CakePHP save()\u00a0to update an arbitrary row unless the loaded ID is re-pinned.<\/p>\n
Severity: 9.4 | CRITICAL<\/p>\n
