CVE-2026-57869
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedBroken object-level access controls and the use of a deterministic pattern during random ID generation in MicroRealEstate allows attackers to access documents uploaded by landlords or tenants without authorization. This issue affects MicroRealEstate: through 1.0.0-alpha3.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceMicroRealEstate versions through 1.0.0-alpha3 contain broken object-level access controls (IDOR) allowing unauthorized access to landlord/tenant documents via predictable resource identifiers. Additionally, the random ID generation uses a deterministic pattern, enabling attackers to enumerate and access documents belonging to other users by predicting valid document IDs.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify MicroRealEstate versionLocate the application version file or package metadata (e.g., package.json, VERSION file, or admin dashboard about page) and compare the installed version to 1.0.0-alpha3. Any version at or below 1.0.0-alpha3 is in the affected range.Affected if Installed version is 1.0.0-alpha3 or lower
-
Confirm document management module is activeVerify that landlord or tenant document upload, viewing, or management features are enabled in the deployment. Check application configuration or module registry.Affected if Document management features for landlords or tenants are accessible to users
-
Test document access authorizationCreate two different user accounts (e.g., landlord A and landlord B). As user A, obtain a valid document ID from your own uploaded document. Then, as user B, attempt to access user A's document using that ID via the document endpoint (e.g., GET /api/documents/{id} or similar).Affected if User B can successfully view or download user A's documents without receiving a 403 Forbidden or unauthorized error
-
Inspect resource identifier randomnessGenerate multiple document IDs by uploading several documents and examine the ID format. Check if IDs follow a sequential pattern, time-based pattern, or other predictable algorithm (e.g., IDs increment by 1, contain timestamps, or use base64-encoded sequential numbers).Affected if Document IDs are sequential, time-based, or otherwise predictable rather than cryptographically random
If the installed version is 1.0.0-alpha3 or lower, document features are enabled, and unauthorized users can access or enumerate other users documents due to missing authorization checks or predictable IDs, the environment is affected by this CVE.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper authorization checks to verify the requesting user owns or has permission to access the requested document, and replace deterministic ID generation with cryptographically secure random identifiers (e.g., UUIDs or secure random tokens).
