Windows Snipping Tool leaks sensitive information to unauthenticated network attackers via user interaction, enabling spoofing attacks. The vulnerability affects Windows 10 (versions 1607, 1809, 21H2, 22H2) and Windows 11 (versions 22H3, 23H2, 24H2, 25H2, 26H1), as well as Windows Server 2012 through 2025. Microsoft has released patches for all affected versions; exploitation requires user interaction but no specialized technical knowledge.
Improper link resolution in Windows UPnP (upnp.dll) allows authenticated local attackers to disclose sensitive information through symlink following. The vulnerability affects Windows 10 versions 1607-22H2, Windows 11 versions 22H3-26H1, and Windows Server 2012-2025. With local access and standard user privileges, an attacker can read files outside their normal access scope via crafted UPnP operations. Patch available from Microsoft; no public exploit code or active exploitation confirmed at tim
Heap-based buffer overflow in Windows USB Print Driver allows local privilege escalation via physical device access. Affects Windows 11 (versions 24H2, 25H2, 26H1) and Windows Server 2025, with patch available from Microsoft. Attack requires physical USB access and no user interaction; no public exploit identified at time of analysis.
Windows Virtualization-Based Security (VBS) Enclave in Windows 11 (versions 24H2, 25H2, 26H1) and Windows Server 2025 allows high-privileged local attackers to bypass security features through improper access control, resulting in integrity compromise without requiring user interaction. A vendor-released patch is available from Microsoft's security updates.
