CVE-2026-57869Network attack vector

Authenticated document disclosure via predictable organization IDs

Published Jul 7, 2026 · Updated Jul 7, 2026

Broken object-level authorization in MicroRealEstate 1.0.0-alpha3 and earlier allows remote authenticated users to read other users' documents. The Documents API uses deterministically generated organization identifiers with reduced entropy as lookup keys and permits brute-forcing them to retrieve uploads across organizations. A network-reachable authenticated account is required; the documented consequence is disclosure of landlord and tenant documents, not modification or service interruption.
