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.

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. Check if Microsoft Word is installed
    Open Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select DisplayName, DisplayVersion' in PowerShell to list installed Microsoft Office products.
    Affected if Microsoft Word does not appear in the installed programs list, then the system is not affected by this vulnerability in Word.
  2. Identify the installed Word version
    Open Word, go to File > Account > About Word, or run 'winword.exe /?' from Command Prompt to display the version information.
    Affected if The displayed version does not match 2013, 2016, 2019, or 2021 (including LTSC), or is not part of Microsoft 365 Apps, then it may not be affected.
  3. Confirm the specific Office/Word build
    Check the registry key HKLM\Software\Microsoft\Office\ClickToRun\Configuration (for Microsoft 365/Office 2016+) or HKLM\Software\Microsoft\Office\[version]\Word\InstallRoot\Path (for Office 2013/2016) to locate the installed Office version and build number.
    Affected if The build number does not correspond to an affected Microsoft 365 Apps, Office 2019, Office 2021 LTSC, Word 2013, or Word 2016 version.
  4. Determine if the affected Office subscription or license type is in use
    In Word, go to File > Account to see if it is a Microsoft 365 Apps subscription, Office 2019 perpetual, Office 2021 LTSC, or a standalone Word 2013/2016 license.
    Affected if The product is not one of the listed affected versions (Microsoft 365 Apps, Office 2019, Office 2021 LTSC, Word 2013, or Word 2016).

A user is affected if they have Microsoft Word installed and their specific version matches Microsoft 365 Apps (any version), Office 2019, Office 2021 LTSC, Word 2013, or Word 2016.
