CVE-2026-61474Network attack vector

Sharing metadata manipulation via distribution-gated authorization

Published Jul 9, 2026 · Updated Jul 9, 2026

Incorrect authorization in MISP 2.5.42 and earlier allows remote authenticated users to associate attributes with unauthorized sharing groups. AttributesController.php calls __canUseSharingGroup only when distribution equals 4, rather than whenever sharing_group_id is supplied. Attribute-creation permission is required; exploitation can corrupt sharing metadata and expose restricted sharing-group relationships.
