Microsoft Edge Security Issues Raise Cyber Threat Concerns, CERT-In Advises Immediate Update
CERT-In has warned of high-severity security vulnerabilities in Microsoft Edge that could allow cyber attacks via malicious websites, urging users to update the browser immediately to protect data and system security.
A new security warning has been issued for Microsoft Edge users, raising concerns among both individuals and corporations. CERT-In, India's cyber security agency, has identified various vulnerabilities in the browser and assessed the issue as high severity, indicating that the risk should not be neglected.
Microsoft Edge is pre-installed on Windows PCs, therefore millions of users could be affected. Although Edge is based on the same Chromium engine as Chrome, it provides additional features and AI tool such as Copilot. These updates make the browser more powerful, but they can also raise security concerns if flaws are discovered.
According to CERT-In’s bulletin dated January 23, 2026, the security issues affect some of the most important parts of the Microsoft Edge browser, including its core processing engine, page rendering system, download handling, network controls, and graphics components. These flaws weaken how the browser checks and processes data, making it possible for attackers to take advantage of them. In many cases, users may be tricked into visiting a carefully designed malicious website, without realizing that anything is wrong.
Once a user opens such a webpage, the attacker could use these weaknesses to carry out harmful actions in the background. This may include running malicious code, stealing sensitive information such as saved data or browsing details, or interfering with how the browser communicates with the operating system. Because a web browser acts as a gateway between the internet and the system, exploiting these vulnerabilities can lead to serious security risks, potentially affecting both personal data and overall system stability.
CERT-In has issued a warning that all users running older versions of Microsoft Edge are vulnerable. This comprises home users, professionals, and enterprises that rely on Edge for their daily tasks. If your browser version is older than 144.0.3719.82, your system may be vulnerable to cyber attacks. This is especially dangerous for users who visit unfamiliar websites, open suspicious links, or use the browser for work-related tasks containing sensitive information.
Updating Microsoft Edge is straightforward and highly recommended for increased security. On your Windows PC, launch Microsoft Edge, click the three-dot menu in the upper right corner, then Help and Feedback, and then About Microsoft Edge. The browser will automatically check for updates and install the most recent version, and you only need to restart it for the changes to take effect.
Browser updates fix known security flaws and protect users from cyber threats, malware, and data theft. Keeping Microsoft Edge updated is one of the easiest ways to stay safe online. In short, if you use Microsoft Edge, updating now is critical to protect your system and personal data from potential attacks.
