CVE-2019-13684
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 · uneditedInappropriate implementation in JavaScript in Google Chrome prior to 72.0.3626.81 allowed a remote attacker to leak cross-origin data 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 · moderate confidenceA cross-origin data leak vulnerability existed in Chrome's JavaScript engine before version 72.0.3626.81. A remote attacker could use a crafted HTML page to bypass same-origin policy protections and leak sensitive data from other origins due to an inappropriate implementation in JavaScript.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Google Chrome versionOpen Google Chrome and navigate to chrome://version, or click the menu icon (three dots) > Help > About Google Chrome. The version number is displayed at the top of the page.Affected if The displayed version number is lower than 72.0.3626.81
-
Confirm the full version stringOn the chrome://version page, note the complete version string (e.g., 72.0.3626.80). Compare the four numeric segments against 72.0.3626.81.Affected if The first segment is less than 72, OR the first segment equals 72 but the second segment is less than 0, OR the first two segments equal 72.0 but the third segment is less than 3626, OR segments 1-3 equal 72.0.3626 but the fourth segment is less than 81
-
Check if the browser is used to visit web pagesThis vulnerability is triggered when a user visits a specially crafted HTML page hosted on an attacker-controlled domain.Affected if The user runs an affected version AND uses the browser to navigate to untrusted websites
The environment is affected if Google Chrome version 72.0.3626.81 or higher is not installed, as the cross-origin data leak flaw exists in earlier versions.
