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. Determine installed Chrome version
    Open Chrome, click the three-dot menu, go to Help > About Google Chrome, or navigate to chrome://settings/help
    Affected if The displayed version number is less than 83.0.4103.61
  2. Check Chrome version via command line (optional)
    On Windows, open Command Prompt and run: chrome --version or look in C:\Program Files\Google\Chrome\Application\ for the version folder. On macOS, run: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version in Terminal. On Linux, run: google-chrome --version or /opt/google/chrome/google-chrome --version
    Affected if The reported version is less than 83.0.4103.61

If the installed Google Chrome version is lower than 83.0.4103.61, the environment is vulnerable to domain spoofing via malformed URLs.
