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 installed Google Chrome version
    Open Chrome, click Help > About Google Chrome, or navigate to chrome://settings/help
    Affected if The displayed version is less than 116.0.5845.110
  2. Verify Chrome version via command line (optional)
    On Windows: Run 'reg query "HKEY_CURRENT_USER\Software\Google\Chrome\BLBeacon" /v version' or check chrome.exe --version. On macOS: Run '/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version'. On Linux: Run 'google-chrome --version' or 'google-chrome-stable --version'
    Affected if The returned version number is below 116.0.5845.110
  3. Check if running affected Fedora version
    Run 'cat /etc/fedora-release' to identify the Fedora version
    Affected if Running Fedora 37, 38, or 39 with an older Chrome package installed
  4. Check if running affected Debian version
    Run 'cat /etc/debian_version' to identify the Debian version
    Affected if Running Debian 11.0 or 12.0 with an older Chrome package installed

You are affected if Google Chrome is installed and its version is below 116.0.5845.110, regardless of operating system.
