The Indian government's cybersecurity agency, CERT-In, has issued a critical security warning for users of Google Chrome and Mozilla Firefox browsers. It has been found that older versions of these browsers contain serious vulnerabilities that hackers could exploit to steal sensitive data or install malicious software.

For Google Chrome, versions older than 141.0.7390.54 (Linux) and 141.0.7390.54/55 (Windows and macOS) have multiple security issues such as heap buffer overflows in WebGPU and Video components, data leaks in Storage and Tab features, and misimplementations in Media and Drumbox. These flaws can allow attackers to redirect users to harmful websites, execute unauthorized code, and access private information.

Similarly, Mozilla Firefox users with versions below 143.0.3 (and below 143.1 on iOS) are at risk due to problems like improper cookie storage isolation, integer overflow errors, and JavaScript engine miscompilation, potentially allowing hackers to take control and steal browser-stored data.

CERT-In has classified these threats as high risk and urges users to immediately update their browsers to the latest versions. Both Google and Mozilla have already released security patches to fix these vulnerabilities. Users are advised to visit the CERT-In official website for detailed information about the vulnerabilities and links to the patches.
