The Indian Computer Emergency Response Team (CERT-In) has issued a high-severity warning to millions of Google Chrome users, urging them to take immediate action. The notice, made public on October 30, 2025, by the Ministry of Electronics and Information Technology, indicates that the presence of multiple severe security vulnerabilities in Chrome. These risks may allow hackers to obtain sensitive information or remotely access the targeted systems.
CERT-In stated that “multiple vulnerabilities have been reported in Google Chrome that could allow a remote attacker to execute arbitrary code, bypass security restrictions, perform spoofing attacks, or disclose sensitive information on the targeted system.” The advisory classifies the issue as high risk and applies to all organizations and individuals using Chrome for desktop.
The vulnerabilities expose users to potential data breaches, unauthorized access, and system hijacking. CERT-In highlighted a most likely occurrence of remote code execution and privilege escalation, suggesting that hackers could gain complete control of the system or expose sensitive data.
The problems are caused by the flaws in Chrome’s core components, such as V8, Extensions, App-Bound Encryption, and Autofill, among others.
Users on Windows, macOS, and Linux are at risk if they are using older versions of Chrome.
CERT-In highlighted that the following builds are affected:
Google Chrome versions before 142.0.7444.59 for Linux
Google Chrome versions before 142.0.7444.59/60 for Windows and Mac
Google Chrome versions before 142.0.7444.60 for Mac
Users should immediately install the latest version of Chrome to patch these vulnerabilities.
To update Google Chrome:
Open the browser and click the three-dot menu on the top right.
Select Settings > About > Update Chrome.
Completing the update requires you to relaunch your browser.
CERT-In strongly recommends that users be aware of these cyber threats and secure their sensitive data by regularly updating their browsers, plugins, and extensions.
The CERT-In Security Warning draws attention to numerous technical errors, including type confusion, race conditions, and use-after-free bugs in the Chrome codebase. Although these flaws are not easy to understand, the essence is clear: if you are using an outdated version of Chrome, your system may be at risk.
The Ministry of Electronics and Information Technology is still closely monitoring browser-related vulnerabilities. Users are advised to follow official advisories and stay vigilant for new updates to keep their data safe.
