CISA has issued an urgent warning about a zero-day vulnerability in Google Chrome that's already being exploited by attackers. The flaw, CVE-2025-13223, affects Chrome's V8 JavaScript engine and allows hackers to execute malicious code remotely just by tricking users into visiting compromised websites. The vulnerability impacts Chrome versions before 131.0.6778.72 and extends to other Chromium-based browsers like Microsoft Edge and Brave. Google patched the issue on November 19, 2025, but CISA has given federal agencies until December 10 to update their systems. With over 3 billion Chrome users worldwide, this high-severity bug poses massive risks for data breaches and malware infections. Users should immediately update to the latest Chrome version to protect themselves. **Source:** [Cybersecurity News](https://cybersecuritynews.com/cisa-warns-chrome-0-day-vulnerability-exploited/)
