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 · unedited
MicroRealEstate is affected by broken object-level access controls in PDF generator functionality. 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 confidence

Broken object-level access control (BOLA/IDOR) vulnerability in the PDF generator allows unauthorized access to or generation of PDF documents that should be restricted. The vulnerability exists in MicroRealEstate through version 1.0.0-alpha3.

MitigationImplement proper authorization checks on all PDF generation endpoints to verify user permissions before allowing access to or generation of PDF documents.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify MicroRealEstate installation
    Locate the MicroRealEstate application directory or check installed packages using system package managers or container image inspection
    Affected if MicroRealEstate is present on the system at any version up to and including 1.0.0-alpha3
  2. Determine installed version
    Check the application version file, metadata, or version string within the installation (commonly found in version files, package.json, about pages, or application headers)
    Affected if The installed version is 1.0.0-alpha3 or any earlier version (including alpha, beta, or release candidates)
  3. Verify PDF generation feature is in use
    Inspect application configuration files, enabled modules, or feature flags to determine if the PDF generator module is activated
    Affected if The PDF generator module is enabled or has been used at least once
  4. Review access logs for PDF endpoint anomalies
    Examine application and web server logs for access patterns to PDF generation or viewing endpoints, focusing on requests from unexpected users or unauthorized document access
    Affected if Log entries show PDF access or generation requests from users who should not have permission to access those documents
  5. Check for unauthorized PDF files
    Inspect the PDF output directory or document storage location for files that may have been generated by users without proper permissions
    Affected if PDF documents exist that were created by or for users who should not have had authorization to generate or access them

The environment is affected if MicroRealEstate version 1.0.0-alpha3 or lower is installed and the PDF generator feature is enabled, regardless of whether exploitation is observed in logs
