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
Insufficient policy enforcement in V8 in Google Chrome prior to 14.0.0.0 allowed a remote attacker to obtain potentially sensitive information from process memory 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.

dbcve analysis · high confidence

This is an information disclosure vulnerability in Google Chrome's V8 JavaScript engine. The vulnerability stems from insufficient policy enforcement in V8 that allowed a remote attacker to craft a malicious HTML page capable of accessing potentially sensitive information directly from process memory.

MitigationUpgrade Google Chrome to version 14.0.0.0 or later to obtain the patch that enforces proper V8 policy restrictions. Organizations should deploy browser updates through their patch management infrastructure.

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
    Open Google Chrome, click the wrench icon (or three-dot menu), select 'About Google Chrome' to view the version number displayed on the page
    Affected if The displayed version is any version before 14.0.0.0 (e.g., 13.x, 12.x, or earlier)
  2. Verify Chrome version via command line
    On Windows, open Command Prompt and run: reg query "HKEY_CURRENT_USER\Software\Google\Chrome\BLFeature" /v Version On macOS, run: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version On Linux, run: google-chrome --version
    Affected if The version output shows a number lower than 14.0.0.0

You are affected if Google Chrome is installed with any version prior to 14.0.0.0, as the V8 JavaScript engine policy flaw exists in those versions.
