CVE-2026-14142
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 Extensions in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to perform UI spoofing via a crafted HTML page. (Chromium security severity: Low)
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 confidenceUI spoofing vulnerability in Chrome extensions where a remote attacker with a compromised renderer process can perform UI spoofing via a crafted HTML page. The vulnerability exists in Chrome versions prior to 150.0.7871.47 and requires the renderer process to already be compromised.

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 use 'About Google Chrome' in the Chrome menu to view the installed version numberAffected if The installed version is less than 150.0.7871.47
-
Verify Chrome extension behaviorReview installed extensions in chrome://extensions and look for any extensions with suspicious or unexpected behavior, especially those with broad permissionsAffected if Suspicious or unauthorized extensions are installed that could indicate a compromised renderer process
-
Check for renderer process anomaliesOpen Chrome's task manager (Shift+Esc) and examine running renderer processes for any with unusual characteristics, high CPU usage, or unexpected network activityAffected if Renderer processes show signs of compromise such as unexpected behavior or connection to malicious servers
-
Inspect Chrome's crash reportsCheck for any recent crash reports in the system that might indicate renderer process exploitation attemptsAffected if Recent renderer process crashes or hang reports exist without obvious cause
You are affected if Chrome version is below 150.0.7871.47 AND a renderer process has been compromised, enabling UI spoofing via crafted HTML pages in extensions.
