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 click Menu > Help > About Google Chrome to view the current version number
    Affected if The displayed version is below 15.0.874.102
  2. Confirm Web Workers are accessible
    Web Workers are enabled by default in Chrome. No user action required - the vulnerability exists in the worker process initialization regardless of explicit configuration
    Affected if Web Workers can be created via JavaScript (standard feature in all affected versions)
  3. Identify if untrusted web content is processed
    The attack vector requires a user to visit or interact with a webpage containing crafted HTML/JavaScript that spawns malicious Web Workers
    Affected if Users can browse arbitrary websites or render untrusted HTML/JS content in the Chrome browser

You are affected if your installed Google Chrome version is lower than 15.0.874.102 and the browser processes untrusted web content.
