A new Chrome zero day update arrived only a few days ago, and it fixes a dangerous flaw that attackers already started using in the wild. Because the exploit works the moment you visit a malicious webpage, you should update your browser as soon as possible to stay protected.
What this zero-day does
The vulnerability, known as CVE-2025-13223, affects Chrome’s V8 JavaScript and WebAssembly engine. Attackers created malicious pages that confuse how the engine handles certain data. As a result, the exploit corrupts memory and opens the door for code execution on your device.
Since the attack triggers as soon as the page loads, users can fall victim without clicking anything else. This makes the issue extremely serious.
How attackers are using it in the wild
Hackers reacted quickly and launched real attacks soon after discovering the flaw. They built harmful websites, used fake ads, and sent phishing links designed to lure users. When someone visits one of these pages, the exploit runs instantly.
This flaw also marks the seventh zero-day patched in Chrome this year. Because of this pattern, keeping your browser updated has become more important than ever.
Why this Chrome zero-day matters
This exploit allows hackers to run code directly through the browser. Once that happens, they can steal information, take over sessions, install malware, or try to penetrate deeper into your system.
Since browsers handle so much of our daily activity, including banking, email, and work apps, a browser-level exploit poses a major threat. Even users on other Chromium-based browsers like Edge, Brave, and Opera should update immediately because they share the same engine.
What you should do right now
To protect yourself, take these steps:
- Install the Chrome zero day update immediately.
- Restart the browser so the patch activates.
- Update other Chromium browsers on your devices.
- Stay cautious with links and websites until attack activity cools down.
- If you manage systems at work, push the update across every machine.
By updating promptly, you significantly reduce the chance of falling victim to this exploit.
