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 Chrome version
    Navigate to chrome://settings/help or run 'google-chrome --version' in terminal
    Affected if Version number is less than 139.0.7258.127
  2. Verify Chrome is the browser in use
    Confirm Google Chrome browser is installed and used for web browsing
    Affected if Chrome browser is present on the system and used
  3. Confirm V8 engine is accessible
    This is inherent to Chrome usage - V8 is always active when Chrome processes JavaScript
    Affected if Chrome browser is actively used to render web content

User is affected if Google Chrome version is below 139.0.7258.127 and the browser is used to process untrusted web content
