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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
