Indian Computer Emergency Response Team (CERT-In) has issued a high-severity advisory flagging a dangerous vulnerability in Microsoft Edge and has urged individuals, enterprises, and government departments to apply updates immediately.
According to the alert, the flaw could allow attackers to execute arbitrary code, bypass security restrictions, or gain access to sensitive information simply by convincing a user to visit a malicious website. Because browsers sit at the frontline of internet activity, exploitation risk is considered significant.
What makes the warning urgent is the browser’s deep integration with enterprise identity, cloud apps, and collaboration environments. A successful compromise may become a gateway into email, documents, and internal systems, amplifying the blast radius beyond a single device.
CERT-In noted that threat actors increasingly weaponize browser bugs soon after disclosure. Automated exploit kits, phishing lures, and drive-by downloads can turn an unpatched machine into an entry point within hours, particularly in hybrid work environments.
The advisory reinforces a familiar lesson: patch latency equals exposure. Many organisations run staggered update cycles for compatibility reasons, but adversaries rely on precisely these delays to scale intrusions.
Users are advised to upgrade to the latest version, enable automatic updates, and review endpoint protection telemetry for unusual browser behavior. Administrators should also verify privilege controls and network segmentation.
As India accelerates digital adoption, timely remediation remains one of the most cost-effective cyber defenses. The message is clear—update now, or risk becoming the next incident headline.
