CVE-2025-65046 is a spoofing vulnerability identified in Microsoft Edge for Android, specifically version 1.0.0. The vulnerability allows an attacker to craft malicious web content that can deceive users by manipulating the browser's user interface, potentially causing users to believe they are interacting with legitimate content when they are not. This type of vulnerability is classified as a spoofing attack, which primarily impacts the integrity of the user interface and user trust rather than confidentiality or availability of data. According to the CVSS 3.1 vector, the attack vector is network-based (AV:N), with high attack complexity (AC:H), no privileges required (PR:N), and requires user interaction (UI:R). The scope remains unchanged (S:U), and the impact on confidentiality is none (C:N), integrity is low (I:L), and availability is none (A:N). The exploitability is limited by the high complexity and the need for user interaction, meaning attackers must convince users to engage with crafted content. No known exploits are currently in the wild, and no patches have been released, indicating the vulnerability is newly disclosed. The vulnerability was reserved in November 2025 and published in December 2025. The lack of patches means users remain exposed until Microsoft issues an update. This vulnerability is specific to the Android version of Microsoft Edge and does not affect other platforms. Spoofing vulnerabilities can be leveraged in phishing campaigns or social engineering attacks to trick users into divulging sensitive information or performing unintended actions.

For European organizations, the impact of CVE-2025-65046 is relatively low but non-negligible. The vulnerability could be exploited to conduct phishing or social engineering attacks by presenting deceptive browser interfaces, potentially leading to credential theft or unauthorized actions if users are tricked. However, since the vulnerability does not affect confidentiality or availability directly and requires user interaction with high attack complexity, the risk is limited. Organizations with a significant mobile workforce using Microsoft Edge on Android devices could see targeted attempts to exploit this flaw. The integrity of user interactions could be compromised, undermining trust in web applications accessed via the browser. This could have downstream effects on corporate security if attackers leverage spoofing to gain initial access or deliver malware. The absence of known exploits and patches reduces immediate risk but emphasizes the need for vigilance. Overall, the threat is low but should be integrated into mobile device management and security awareness programs.

1. Monitor official Microsoft security advisories and promptly apply any patches or updates released for Microsoft Edge on Android. 2. Implement mobile device management (MDM) policies to control browser versions and enforce timely updates. 3. Educate users about the risks of interacting with suspicious links or content, emphasizing caution when browsing unknown websites on mobile devices. 4. Employ security solutions that can detect phishing and spoofing attempts at the network or endpoint level, including mobile threat defense platforms. 5. Restrict installation of applications and browsers to approved versions via enterprise app stores or MDM controls. 6. Encourage use of multi-factor authentication (MFA) to mitigate potential credential compromise resulting from spoofing attacks. 7. Conduct regular security awareness training focusing on recognizing spoofed interfaces and social engineering tactics. 8. Monitor network traffic for unusual patterns that may indicate exploitation attempts. 9. Consider deploying browser security extensions or configurations that limit the ability of malicious sites to manipulate UI elements. 10. Maintain an incident response plan that includes procedures for handling suspected spoofing or phishing incidents on mobile devices.
