Google Chrome, the world’s most popular browser with over 3.5 billion users, faces a critical security threat. A high-severity vulnerability in Chrome’s V8 JavaScript engine (CVE-2025-6554) has been exploited by hackers, prompting urgent calls for users to update their browsers immediately.
The Vulnerability Explained
The flaw in Chrome V8—a core component that processes website code—allowed attackers to create malicious webpages capable of stealing sensitive data (like passwords), injecting ransomware, or compromising devices. Cybersecurity experts warn this “zero-day” exploit (a flaw unknown to developers until abused) was actively exploited, possibly by nation-state actors. Google’s Threat Analysis Group (TAG), which monitors advanced cyber threats, identified the issue, hinting at sophisticated attackers targeting high-value individuals.

Severity and Risks
Rated 8.1/10 in severity, the vulnerability allows “read/write” access to a device’s memory. Jake Moore, ESET Cybersecurity Advisor, warns, “Hackers could steal passwords stored in the browser, then target the victim’s contacts.” Similar flaws have historically been used to spy on journalists, activists, and government staff, akin to the Pegasus spyware attacks.
How to Update Chrome
Google has patched the issue in version 138.0.7204.96/.97 (Windows), 138.0.7204.92/.93 (macOS), and 138.0.7204.96 (Linux). To update:
- Click the three-dot menu > Help > About Google Chrome.
- If an update is pending, select Relaunch.
- No “Relaunch” button means you’re already protected.

Stay Vigilant
While Chrome auto-updates, users should manually verify their version. Google advises against sharing details until most users are protected. For broader security, regularly check compromised accounts on Have I Been Pwned and use password managers with two-factor authentication.
Stay informed, update promptly, and safeguard your digital life.
