CVE-2025-65046 is a spoofing vulnerability identified in Microsoft Edge for Android, specifically affecting version 1.0.0 of the Chromium-based browser. The vulnerability is categorized under CWE-290, which relates to improper authentication or validation issues that can lead to spoofing attacks. In this context, the flaw allows an attacker to manipulate the browser's UI or content presentation to deceive users, potentially causing them to trust malicious content or links. The CVSS v3.1 base score is 3.1, indicating low severity, with the vector string AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C. This means the attack can be launched remotely over the network without requiring privileges but needs user interaction and has high attack complexity, reducing the likelihood of successful exploitation. The impact is limited to integrity, with no direct confidentiality or availability consequences. No known exploits have been reported in the wild, and no official patches have been released at the time of publication. The vulnerability's presence in the Android version of Microsoft Edge is significant because mobile devices are widely used for browsing, and spoofing attacks can facilitate phishing or social engineering campaigns. The lack of patches means users and organizations must rely on interim mitigations until Microsoft issues an update. The vulnerability's classification as spoofing suggests attackers could craft deceptive URLs or UI elements to trick users into revealing sensitive information or performing unintended actions.

For European organizations, the primary impact of CVE-2025-65046 lies in the potential for phishing and social engineering attacks leveraging spoofed content within Microsoft Edge on Android devices. This could lead to compromised user trust, credential theft, or unauthorized actions if users are deceived by falsified UI elements. While the vulnerability does not directly compromise confidentiality or availability, the integrity impact can indirectly lead to data breaches or fraud. Organizations with mobile-first workforces or those relying heavily on Android devices for web access are at greater risk. The low severity and high attack complexity reduce the likelihood of widespread exploitation, but targeted attacks against high-value individuals or sectors such as finance, government, or critical infrastructure could still pose a threat. The absence of known exploits in the wild currently limits immediate risk, but the situation could evolve once exploit code becomes available or if attackers develop sophisticated social engineering campaigns.

1. Monitor official Microsoft communications and security advisories for patches addressing CVE-2025-65046 and apply updates promptly once available. 2. Educate users about the risks of spoofing attacks, emphasizing caution when interacting with unexpected or suspicious links and UI elements, especially on mobile browsers. 3. Implement mobile device management (MDM) solutions to enforce security policies, restrict installation of untrusted applications, and control browser configurations. 4. Use advanced threat protection tools that can detect and block phishing attempts and malicious URLs in real-time on mobile devices. 5. Encourage the use of multi-factor authentication (MFA) to reduce the impact of credential compromise resulting from spoofing attacks. 6. Conduct regular security awareness training focused on mobile security and social engineering tactics. 7. Consider deploying network-level protections such as DNS filtering and secure web gateways to reduce exposure to malicious sites. 8. For critical users, consider restricting the use of vulnerable browser versions or providing alternative secure browsing options until patches are available.
