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
    Navigate to chrome://settings/help or use 'Help > About Google Chrome' to view the version number
    Affected if The displayed version is less than 69.0.3497.81
  2. Verify Chrome is used for browsing
    Confirm that Google Chrome is the primary or configured browser for rendering HTML content in the environment
    Affected if Chrome is used and the version from step 1 is below 69.0.3497.81
  3. Confirm Skia rendering component is active
    Skia (libskia.dll on Windows, libskia.dylib on macOS, libskia.so on Linux) is built into Chrome and loads automatically when rendering any web page
    Affected if Chrome processes HTML content and version is below 69.0.3497.81

If Google Chrome version is below 69.0.3497.81, the environment is vulnerable when Chrome renders HTML content including untrusted pages.
