CVE-2024-7021 is a vulnerability identified in the Autofill implementation of Google Chrome on Windows platforms prior to version 124.0.6367.60. The flaw stems from an inappropriate implementation that enables remote attackers to conduct UI spoofing attacks by delivering a crafted HTML page. UI spoofing involves deceiving users by presenting fake or manipulated interface elements that appear legitimate, potentially tricking users into divulging sensitive information or performing unintended actions. This vulnerability is classified under CWE-451 (Incorrect Expression of User Interface in a Security Decision), indicating a failure in properly representing UI elements securely. The attack vector is network-based (AV:N), requiring no privileges (PR:N), but does require user interaction (UI:R), such as visiting a malicious webpage. The scope is unchanged (S:U), and the impact is limited to availability (A:L), with no direct confidentiality or integrity compromise. The CVSS v3.1 base score is 4.3, reflecting medium severity. Although no known exploits are currently reported in the wild, the potential for phishing or social engineering attacks leveraging this spoofing vulnerability exists. The vulnerability was publicly disclosed on November 14, 2025, and Google has released an update to address the issue in Chrome version 124.0.6367.60. Organizations relying on Chrome for web access should ensure prompt patching to prevent exploitation.

For European organizations, this vulnerability primarily poses a risk of UI spoofing attacks that can facilitate phishing or social engineering campaigns. While it does not directly compromise data confidentiality or integrity, successful exploitation could lead to users being tricked into revealing credentials or other sensitive information, indirectly impacting security posture. The availability impact is low but could cause browser instability or denial of service in targeted scenarios. Given the widespread use of Google Chrome across European enterprises and public sectors, especially in countries with high digital service adoption, the risk of targeted attacks exploiting this vulnerability is notable. Attackers could leverage this flaw to impersonate trusted interfaces, increasing the effectiveness of malicious campaigns. The absence of known exploits reduces immediate risk, but the medium severity rating and ease of exploitation through crafted web content necessitate proactive mitigation. Organizations involved in finance, government, and critical infrastructure sectors are particularly sensitive to UI spoofing due to the potential for fraud or unauthorized access.

European organizations should implement the following specific mitigation steps: 1) Immediately update all Google Chrome installations on Windows devices to version 124.0.6367.60 or later to apply the official patch. 2) Enforce enterprise-wide browser update policies and automate patch deployment to minimize exposure windows. 3) Educate users about the risks of UI spoofing and train them to recognize suspicious web pages and avoid interacting with unexpected prompts or forms. 4) Deploy web filtering solutions to block access to known malicious or suspicious websites that could host crafted HTML pages exploiting this vulnerability. 5) Utilize endpoint protection tools capable of detecting anomalous browser behavior indicative of UI spoofing attempts. 6) Monitor network traffic and browser logs for unusual patterns that may suggest exploitation attempts. 7) Consider implementing multi-factor authentication (MFA) on critical web services to reduce the impact of credential theft resulting from spoofing attacks. 8) Coordinate with IT and security teams to conduct phishing simulations and reinforce awareness of social engineering tactics leveraging UI spoofing.
