CVE-2026-13947
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 · uneditedUninitialized Use in XR in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium)
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 confidenceUninitialized memory read vulnerability in Chrome's XR (WebXR) component. A remote attacker who has already compromised the renderer process can exploit this flaw via a crafted HTML page to read potentially sensitive information from process memory.

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 versionNavigate to chrome://settings/help or run 'google-chrome --version' in terminal to view the installed version numberAffected if Version is below 150.0.7871.47
-
Verify WebXR feature statusNavigate to chrome://flags/#webxr and inspect the 'WebXR Incubated Features' or 'WebXR' flag setting. Alternatively, check for Group Policy settings under Computer Configuration > Administrative Templates > Google Chrome > WebXRAffected if WebXR is enabled (set to Enabled or Default) on an affected version
-
Confirm XR runtime availabilityCheck for installed XR runtimes (such as Windows Mixed Reality, Oculus, SteamVR) that may register as WebXR presentation providers. On Windows, inspect Registry keys under HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Khronos\OpenXR\1\ApiLayers or review installed XR applicationsAffected if Any XR runtime is installed and WebXR is enabled on an affected Chrome version
User is affected if Chrome version is below 150.0.7871.47 AND WebXR feature is enabled, allowing a compromised renderer to read uninitialized memory via crafted XR content.
