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

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 the installed Cybozu Garoon version
    Access the system administration panel or check the product information page within Cybozu Garoon to determine the exact version number running in your environment
    Affected if The installed version falls within the range 4.0.0 through 5.9.1 (inclusive)
  2. Verify if file management applications are active
    Check the Cybozu Garoon system configuration to determine which applications are enabled, specifically looking for file management, bulletin board, or workflow modules that handle file attachments and metadata
    Affected if File management or related applications that handle file attachments are enabled on the system
  3. Review user access control configurations
    Examine the permission settings for file management features in the administration console to see how user access boundaries are defined
    Affected if Multiple users or groups exist with differentiated permissions to files, and the system relies on these access controls to restrict file operations

You are affected if Cybozu Garoon version 4.0.0 through 5.9.1 is running AND file management functionality is enabled, as the vulnerability allows authorized users to bypass intended access restrictions on file metadata modifications or deletions.
