Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A missing check for JS-simulated input events in Blink in Google Chrome prior to 69.0.3497.81 allowed a remote attacker to download arbitrary files with no user input via a crafted HTML page.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

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 and navigate to chrome://version, or run 'google-chrome --version' from command line
    Affected if The displayed version is earlier than 69.0.3497.81
  2. Check if running a vulnerable Chrome build on RHEL 6
    On RHEL 6 systems, determine the installed Google Chrome package version using the system package manager (e.g., rpm -q google-chrome-stable or yum list installed google-chrome*)
    Affected if The installed Chrome version on RHEL 6.x systems is earlier than 69.0.3497.81
  3. Verify JavaScript is enabled in the browser
    In Chrome, go to Settings > Privacy and security > Site Settings > JavaScript, or navigate to chrome://settings/content/javascript
    Affected if JavaScript is allowed (this is required for the crafted page to trigger the vulnerability)

You are affected if you are running Google Chrome version earlier than 69.0.3497.81 on any system, or running Chrome on RHEL 6.0, with JavaScript enabled in the browser settings.
