Google has issued an urgent security alert for its over two billion Chrome users, warning of a high-severity vulnerability that hackers are already actively exploiting. The company is urging everyone to update their browser immediately to protect their computers.
The flaw, tracked as CVE-2025-13223, is a “type confusion” weakness within Chrome’s V8 JavaScript engine, which is the core component that runs website code.

How the Attack Works
This security hole is particularly dangerous because it can be exploited remotely. An attacker can create a specially designed, malicious website.
If a user visits this site, the bug can corrupt the browser’s memory. This could allow the attacker to execute arbitrary code on the victim’s computer, potentially stealing data or installing malware.
Google’s own Threat Analysis Group (TAG) discovered the exploit in the wild on November 12, confirming that it’s not just a theoretical risk but a live threat.
How to Protect Yourself Immediately
While Chrome usually updates automatically, you must take one crucial step to ensure you are protected.
- Update Your Browser: Go to your Chrome settings (the three dots in the top-right corner), navigate to “Help,” and then “About Google Chrome.” The browser will then check for and install the latest update.
- RESTART CHROME: This is the most important step. The security patch does not activate until you completely close and restart the browser.
Do not delay this simple process. Taking a minute to update and restart your browser can prevent a serious security breach.
Frequently Asked Questions (FAQs)
1. What is a “type confusion” attack?
It’s a coding flaw where the browser is tricked into treating data as one type (e.g., a number) when it is actually another (e.g., text). This confusion can corrupt memory and allow hackers to run their own code.
2. How can I get hacked by this?
Simply by visiting a malicious website. No download is required, making it a very stealthy threat.
3. My browser updates automatically. Am I safe?
You are only safe after the update is installed and you have fully restarted the Chrome browser. Please check your version and restart it to be sure.
4. What is the vulnerability ID?
The specific identifier for this flaw is CVE-2025-13223. You can look this up to find official technical details.
