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
SAP Disclosure Management, version - 10.1, provides capabilities for authorized users to upload and download content of specific file type. In some file types it is possible to enter formulas which can call external applications or execute scripts. The execution of a payload (script) on target machine could be used to steal and modify the data available in the spreadsheet

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 · high confidence

SAP Disclosure Management 10.1 contains a formula injection vulnerability where users can upload files containing formulas capable of calling external applications or executing scripts. When these malicious files are processed or opened, the embedded payload can execute on the target machine, potentially allowing attackers to steal or modify data within spreadsheets.

MitigationImplement strict input validation and sanitization for all uploaded file content, particularly formula characters (=, +, -, @, tab, CR). Consider using safe file formats that do not support formulas, or disable external formula references and script execution in the application's file processing logic.

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. Verify SAP Disclosure Management version
    Check the installed version of SAP Disclosure Management in the application about page, help menu, or system information panel to confirm it is exactly version 10.1
    Affected if Version is exactly 10.1
  2. Confirm file upload functionality is enabled
    Determine whether the file upload or import feature is available and active in the SAP Disclosure Management application interface, typically found in document processing or data import sections
    Affected if File upload or import capability is present and enabled for users
  3. Check if spreadsheet processing accepts formulas
    Test or inspect whether the application allows processing of spreadsheet files (such as .xls, .xlsx, or .csv) that could contain formula characters (=, +, -, @) capable of calling external applications
    Affected if The application processes spreadsheet files that support formula execution

Your environment is affected if you are running SAP Disclosure Management version 10.1 and the application processes or opens uploaded spreadsheet files that can contain executable formulas.
