Windows 10 Version 1809

Privilege escalation via double free in the Windows Rich Text Edit Control (RichEdit) affects an exceptionally broad range of Microsoft platforms, spanning Windows 10 versions 1607 through 22H2, all current Windows 11 branches through 26H1, and Windows Server 2012 through Server 2025. A low-privileged local attacker who can induce user interaction with crafted RTF content can corrupt heap memory to achieve full compromise of confidentiality, integrity, and availability - consistent with the SSVC 'total technical impact' rating. No public exploit code exists and no active exploitation has been identified (not in CISA KEV), and the EPSS score of 0.05% at the 16th percentile reflects a minimal current exploitation signal; however, the sheer scale of the affected Windows install base keeps this relevant for enterprise patch cadence. A notable discrepancy exists: the CVE tags classify this as 'Information Disclosure,' which conflicts with Microsoft's own description of local privilege elevation - the CVSS C:H/I:H/A:H impact metrics and SSVC total-impact rating support the privilege escalation characterization, suggesting the tag is erroneous.
Heap-based buffer overflow in the Windows Volume Manager Extension Driver enables an authorized attacker with physical device access to execute arbitrary code, achieving full system compromise across a broad range of Windows 10, Windows 11, and Windows Server editions. Affected product versions span from Windows Server 2012 through Windows 11 26H1 and Windows Server 2025, per EUVD-2026-29656 data. No active exploitation has been confirmed (not in CISA KEV), and EPSS at 0.07% (22nd percentile) reflects the extremely low probability of widespread exploitation given the dual prerequisite of physical presence and high-privilege credentials.
Out-of-bounds read in the Windows Telnet Client exposes memory contents and minor availability degradation to network-based attackers who control a Telnet server endpoint. Affected systems span Windows 10 (1607 through 22H2), Windows 11 (22H3 through 26H1), and Windows Server 2012 through 2025, all requiring user interaction to initiate a Telnet session against a malicious server. No public exploit identified at time of analysis and no active exploitation confirmed (not in CISA KEV); EPSS stands at 0.05% (16th percentile), reinforcing that real-world exploitation risk is low despite the broad platform footprint.
Windows TCP/IP stack allows a low-privilege network-authenticated attacker to bypass a security feature by exploiting an alternate path or channel (CWE-288), resulting in a high-integrity impact without requiring user interaction. Affected scope spans Windows 10 (versions 1607 through 22H2), Windows 11 (versions 22H3 through 26H1), and Windows Server 2012 through Server 2025, making the exposure footprint extremely broad. No public exploit code exists and no active exploitation is confirmed at time of analysis; EPSS at 0.06% (18th percentile) and SSVC classification of 'exploitation: none, automatable: no' indicate low near-term weaponization risk despite the wide attack surface.
Improper access control in Universal Plug and Play (upnp.dll) on Windows allows authenticated local attackers to disclose sensitive information without user interaction. The vulnerability affects Windows 10 (versions 1607, 1809, 21H2, 22H2), Windows 11 (versions 22H3, 23H2, 24H2, 25H2, 26H1), and Windows Server 2012-2025. Microsoft has released patches available through their security update guide; no public exploit code or active exploitation has been reported at time of analysis.
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.
