A use-after-free vulnerability (CWE-416) in the Desktop Window Manager of Windows 10 version 1809 and Windows Server 2019 allows an authorized local user to elevate privileges. An attacker needs a valid low-privileged account or an existing foothold on the system, but then can gain high impact on confidentiality, integrity and availability. The vulnerability is not reachable directly from the internet.

Microsoft SharePoint Server Subscription Edition contains an elevation of privilege vulnerability (CWE-269, Improper Privilege Management). An attacker with a low-privileged valid account can reach a higher privilege level, potentially gaining administrative control over the affected server. No user interaction is required, and the attack can be carried out over the network. Exposure is greatest for internet-facing farms and farms with many user accounts.

The Windows RPC Runtime Library contains an untrusted pointer dereference that allows an unauthorized attacker to execute code. The CNA describes the attack as network-based. The CVSS vector (UI:R) indicates that a user must interact, and the vendor snippet we could access describes a specially crafted file, so exposure depends on how RPC services and user file handling are reachable. Attack conditions are not fully confirmed.

A security feature bypass vulnerability in Microsoft Office Word relies on untrusted inputs in a security decision (CWE-807). A local, unauthorized attacker may bypass a security feature, for example by getting a user to open a crafted Word document, as the CVSS vector requires user interaction. CVSS 7.8 (High); the vulnerability was published with the October 2026 Microsoft security updates.

Missing authorization checks in Microsoft Office SharePoint allow an authenticated attacker with a low-privileged account to perform operations beyond the permissions granted to that account. The attacker needs network access to an affected server and a valid user account, and the vulnerability is rated High (CVSS 3.1 8.8). Internet-facing farms with many user, external or guest accounts are more exposed.
