republic of india’s cyber certificate bureau, the amerind data processor Emergency Response Team (CERT-In), has issued fresh advisories warning users of macOS and Google Chrome about serious software vulnerabilities that could lead to data theft or complete system compromise if left unpatched.
The alerts highlight weaknesses in Apple’s productivity applications and Google’s desktop browser that may be exploited through malicious documents or specially crafted requests. CERT-In has urged both individuals and organisations to install the latest updates without delay to reduce the risk of unauthorised access and information exposure.
Apple Fixes Flaws in Pages and Keynote
In an advisory released on January 29, CERT-In flagged multiple security issues affecting Apple’s Pages and Keynote applications on macOS. The vulnerabilities impact versions of the apps released before Pages 15.1 and Keynote 15.1.
According to the agency, one of the issues involves an out-of-bounds read error in Pages, while another stems from a flaw in the QuickLook component used by Keynote. These weaknesses could be exploited if users are tricked into opening specially crafted files, potentially allowing attackers to access sensitive data.
Apple has addressed the problems in updated versions of Pages and Keynote released on January 28 for devices running macOS Sequoia 15.6 and newer. The issues are tracked under CVE-2025-46316 and CVE-2025-46306.
High-Severity Chrome Vulnerability Identified
CERT-In has also raised concerns over a high-risk vulnerability in Google Chrome for desktop platforms. The flaw affects Chrome versions earlier than 144.0.7559.109 on Linux and earlier than 144.0.7559.109 or 144.0.7559.110 on Windows and macOS.
The vulnerability is linked to an improper implementation of Chrome’s Background Fetch API. CERT-In warned that attackers could exploit the flaw using a specially crafted request, potentially enabling remote code execution on affected systems.
Classified as a high-severity issue, the vulnerability could result in full system compromise or disruption of services if successfully exploited. Google has resolved the issue in its Stable Channel update released on January 27. The flaw is tracked as CVE-2026-1504.
Users Urged to Update Software Immediately
CERT-In has advised users to promptly install the latest updates released by Apple and Google to mitigate the identified risks. The agency also recommended reviewing official security release notes for detailed information on the fixes and affected systems.
