Technical details
An improper access control vulnerability exists in MISP's attribute search and paginated attribute listing endpoints. When querying for soft-deleted attributes, the application fails to restrict results to the owning organization and sync-permission users, unlike the event detail view which implements these checks correctly. An authenticated attacker with read visibility to an event owned by another organization can enumerate and retrieve soft-deleted threat intelligence attributes by querying the vulnerable endpoints.
