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 Google Chrome version
    Open Chrome, click the three-dot menu > Help > About Google Chrome, or navigate to chrome://settings/help
    Affected if The displayed version is less than 77.0.3865.75
  2. Confirm Blink rendering engine version
    In Chrome address bar, navigate to chrome://version and look for the 'Blink' or 'WebKit' version information
    Affected if The Blink version corresponds to a Chrome build earlier than 77.0.3865.75
  3. Verify no security exceptions or policies
    Check if the browser has any enterprise policies or extensions that modify download behavior by navigating to chrome://policy
    Affected if No special configuration prevents this vulnerability - the flaw is in the rendering engine itself and requires no specific feature to be enabled
