CVE-2025-59294 is a vulnerability classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) affecting Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The flaw resides in the Windows Taskbar Live feature, which can inadvertently disclose sensitive information when an attacker gains physical access to the device. Exploitation requires physical presence and some user interaction, such as triggering the taskbar live feature to reveal information that should otherwise be protected. The vulnerability does not allow remote exploitation, nor does it compromise system integrity or availability. The CVSS v3.1 score is 2.1, reflecting low impact primarily on confidentiality with no impact on integrity or availability, and requiring physical attack vector with low attack complexity but user interaction. No known exploits are currently in the wild, and no official patches have been published as of the vulnerability disclosure date (October 14, 2025). Given that Windows 10 Version 1809 is an older release with extended support ended or nearing end, many organizations have likely migrated to newer versions, reducing the overall exposure. However, legacy systems in operational technology or specialized environments may still be vulnerable. The vulnerability highlights the importance of physical security controls and timely system updates to prevent unauthorized information disclosure through local access.

For European organizations, the impact of CVE-2025-59294 is generally low but context-dependent. The vulnerability could lead to unauthorized disclosure of sensitive information if an attacker gains physical access to a device running Windows 10 Version 1809. This could include exposure of user interface elements or data displayed via the taskbar live feature, potentially leaking confidential information relevant to business operations or user credentials. While the impact on confidentiality is limited and does not extend to system integrity or availability, the risk is heightened in environments with weak physical security, such as shared workspaces, public access areas, or poorly controlled offices. Sectors like government, finance, healthcare, and critical infrastructure in Europe may be more sensitive to such information leaks. The lack of remote exploitability reduces the threat surface, but insider threats or physical theft remain concerns. Organizations still running legacy Windows 10 1809 systems face a higher risk, especially if these devices contain sensitive data or access to critical networks. Overall, the vulnerability poses a minor but non-negligible risk that should be addressed as part of a comprehensive security posture.

1. Upgrade all Windows 10 Version 1809 systems to a supported and patched Windows version to eliminate the vulnerability entirely. 2. Enforce strict physical security controls to prevent unauthorized physical access to devices, including locked rooms, secure desks, and surveillance. 3. Implement endpoint security policies that restrict user interaction with sensitive UI elements, such as disabling unnecessary taskbar live features or notifications that could leak information. 4. Use full disk encryption and screen lock policies to minimize data exposure if physical access is gained. 5. Conduct regular audits of legacy systems to identify and remediate outdated software versions. 6. Train staff on the risks of physical access attacks and encourage reporting of suspicious activity. 7. Monitor for unusual local access attempts or user interactions that could indicate exploitation attempts. 8. If upgrading is not immediately feasible, consider isolating legacy systems from sensitive networks and data to limit potential exposure. These steps go beyond generic advice by focusing on physical security, user interface controls, and legacy system management specific to this vulnerability.
