If you use Google Chrome on Windows, macOS, or Linux, your browser may be vulnerable, and hackers are taking advantage of it right now.
On July 1, 2025, Google released an emergency security update to fix a critical Chrome vulnerability known as CVE-2025-6554. This is not a theoretical threat — it’s a zero-day vulnerability, which means attackers discovered and began exploiting it before Google had a chance to patch it.
What Is the Chrome CVE-2025-6554 Vulnerability?
This flaw lives inside Chrome’s V8 engine, the part of the browser responsible for running JavaScript and web applications. It’s classified as a “type confusion” bug. In simple terms, this bug can confuse the way Chrome processes data, allowing hackers to run harmful code on your computer.
Even worse?
All it takes is visiting a malicious website. You don’t need to click anything suspicious, your browser could be hijacked silently.
Who Is Affected?
If you’re using any version of Chrome before 138.0.7204.96, you are at risk.
This includes users on Windows, macOS, and Linux.
Google has confirmed the flaw is being actively exploited in the wild, which means real people and businesses are already being targeted.
Why It Matters to You
Data Theft: Attackers could access or steal personal and business data.
System Compromise: Your device could be controlled remotely or infected with malware.
Business Disruption: One compromised browser could lead to much bigger security issues across your network.
⚠️ Action Required Immediately
To protect your organization and users, take the following steps as soon as possible:
1. Update Google Chrome
Navigate to chrome://settings/help
Ensure your Chrome version is 138.0.7204.96 or later
Restart your browser after updating
2. Force update across endpoints
IT admins should push Chrome updates via GPO, Intune, or endpoint management tools.
Disable auto-update blocks, if in place.
3. Warn employees
Send a company-wide alert urging users to update Chrome.
Remind employees not to click on suspicious links or unfamiliar websites.
4. Monitor for IOCs (Indicators of Compromise)
Watch for unexpected browser behavior, crashes, or unknown network activity.
Conduct forensic reviews if any users report suspicious behavior
5. Restrict browser use on critical systems
Consider restricting access to web browsers on sensitive machines until patches are verified.
