CVE-2019-13692
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 · uneditedInsufficient policy enforcement in reader mode in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to bypass site isolation 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 confidenceThis vulnerability in Google Chrome's reader mode allowed insufficient policy enforcement, enabling a remote attacker to craft a malicious HTML page that could bypass site isolation protections. Site isolation is a critical security feature that prevents one website from accessing data from another website, so bypassing it could allow data theft across origins.

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.
-
Check installed Chrome versionOpen Chrome, click the three-dot menu > Help > About Google Chrome. The version number is displayed on this page.Affected if The version shown is earlier than 77.0.3865.75 (for example, 77.0.3865.50 or any version below 77.0.3865.75).
-
Confirm Chrome channel and buildIn chrome://version, note the Product version and Channel (stable, beta, dev, or canary). Enterprise-managed Chrome may show additional deployment info.Affected if The version is below 77.0.3865.75 regardless of channel, as this vulnerability affected all builds prior to that patch.
-
Verify reader mode accessibilityChrome's reader mode is accessed via the URL chrome://view-source or by using a reader mode extension. Confirm whether any reader mode functionality is available in the browser.Affected if Reader mode is available and in use on an affected Chrome version, creating the conditions for the policy bypass.
You are affected if your installed Google Chrome version is lower than 77.0.3865.75 and you use or could use reader mode, as the vulnerability allows bypassing site isolation in that feature.
