Google has confirmed that attackers have exploited a high-risk vulnerability in its Chrome browser. Users have been advised to update their browsers before 23 July, with cybersecurity agencies stressing the urgency.
The flaw, CVE-2025-6554, involves a type confusion issue in Chrome's V8 JavaScript engine. The US Cybersecurity and Infrastructure Security Agency (CISA) has made the update mandatory for federal departments and recommends all users take immediate action.
Although Chrome updates are applied automatically, users must restart their browsers to activate the security patches. Many fail to do so, leaving them exposed despite downloading the latest version.
CISA highlighted that timely updates are essential for reducing vulnerability to attacks, especially for organisations managing critical infrastructure. Enterprises are at risk if patching delays allow attackers to exploit known weaknesses.
