In recent times, vulnerabilities in popular web browsers have significantly increased, posing potential threats to users' data and privacy. One such vulnerability, identified by the CVE-2024-26163 code, affects the widely used Microsoft Edge (Chromium-based) web browser. In this blog post, we will inspect the details surrounding this vulnerability, examine the code snippet associated with it, analyze the exploits, and refer to the original references for a deeper understanding.

A brief background on Microsoft Edge (Chromium-based) Web Browser

Microsoft introduced a revamped version of its Microsoft Edge web browser in 202, adopting the popular open-source project, Chromium, as its underlying technology. This new browser has attracted millions of users across the globe with its improved features, extensions, and compatibility. However, like all software products, Microsoft Edge (Chromium-based) has its potential vulnerabilities, one of which we are scrutinizing today.

The Vulnerability: CVE-2024-26163
CVE-2024-26163 is a security feature bypass vulnerability affecting the Microsoft Edge (Chromium-based) web browser. This vulnerability enables potential attackers to exploit certain security mechanisms and gain unauthorized access to sensitive information on a user's device.

Code Snippet

To help you understand the core issue, we've included a sample code snippet that demonstrates the vulnerability:

// Sample JavaScript code simulating the vulnerability
function bypassSecurityFeature() {
    const edgeUserAgent = "Mozilla/5. (Windows NT 10.; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89..4389.82 Safari/537.36 Edg/89..774.50";

    // Exploiting the vulnerability
    if (navigator.userAgent === edgeUserAgent) {
        const unauthorizedAccess = {
            userSensitiveData: "Potential attacker's exploit code goes here",

        console.log("Security feature bypassed!", unauthorizedAccess);

window.addEventListener("DOMContentLoaded", (event) => {

In the example above, the function bypassSecurityFeature() simulates how an attacker could exploit the CVE-2024-26163 vulnerability when executed on a victim's device using the Microsoft Edge browser. Note that this is just a simplified example to demonstrate the concept and does not constitute real-world exploit code.

Exploit Details

The primary exploitation of CVE-2024-26163 relies on bypassing security features in the browser. Attackers can use this vulnerability to intercept and manipulate sensitive information, including login credentials, banking information, and other personal details.

Microsoft has rated the severity of this vulnerability as "Important" and has released patches in subsequent updates. Users are encouraged to update their Microsoft Edge browser to the latest available version to address this vulnerability.

Final Words

Ensuring your software is up-to-date is paramount in safeguarding your digital life against potential threats. To stay protected from this CVE-2024-26163 vulnerability and other security risks, make sure you install security updates regularly and keep your browser version current.
