CVE-2026-57870Network attack vector

Cross-organization template disclosure via unchecked object authorization

Published Jul 7, 2026 · Updated Jul 7, 2026

Broken object authorization in MicroRealEstate 1.0.0-alpha3 and earlier allows remote authenticated users to read other organizations' templates. The Template API retrieves a template selected by an object key without validating that the requested template belongs to the caller's organization. A valid low-privilege account is required, and the demonstrated consequence is reading document templates rather than modifying them or interrupting service.
