Microsoft released fixes for **163 vulnerabilities** in its April Patch Tuesday update, marking one of its largest security releases on record. The bundle includes **8 Critical** flaws, **154 Important** issues, and **1 Moderate** bug, with seven of the Critical vulnerabilities enabling remote code execution across products and components including **Windows TCP/IP**, **Windows IKE Service Extensions**, **Active Directory**, **Remote Desktop Client**, **Microsoft Office**, and **Microsoft Word**. Belgian authorities urged organizations to apply the updates immediately. The most urgent issues include **`CVE-2026-32201`**, an actively exploited **Microsoft SharePoint Server** vulnerability that was added to CISA’s Known Exploited Vulnerabilities catalog, and **`CVE-2026-33825`** in **Microsoft Defender**, a publicly disclosed zero-day tied to proof-of-concept code associated with the **BlueHammer** exploit. Microsoft also shipped Windows 11 cumulative updates with security hardening changes, including safer handling of **`.rdp`** files and improved visibility into **Secure Boot** certificates, while the broader patch set addressed numerous elevation-of-privilege and security feature bypass flaws that could support post-compromise escalation.

Microsoft released fixes for **165 vulnerabilities** across Windows, Office, SharePoint, Defender, SQL Server, Azure, .NET, and other products in one of its largest Patch Tuesday updates on record. The most urgent issue was **CVE-2026-32201**, an **actively exploited** improper input validation flaw in **SharePoint Server** that enables unauthenticated network-based spoofing and was immediately added to **CISA's Known Exploited Vulnerabilities** catalog. Microsoft also patched **CVE-2026-33825**, a publicly known **Microsoft Defender** privilege-escalation bug with proof-of-concept code, and **CVE-2026-33824**, a critical **remote code execution** flaw in **Windows IKE Service Extensions** affecting IPsec/VPN infrastructure. Researchers flagged **CVE-2026-33827** in **Windows TCP/IP** as potentially **wormable** under certain IPv6 and IPSec configurations. Other high-impact fixes include **CVE-2026-33120**, a **SQL Server remote code execution** flaw that paired with a separate privilege escalation bug (**CVE-2026-32176**) could enable full server compromise, and **CVE-2026-32220**, a **UEFI Secure Boot bypass** that could allow untrusted code to load during the boot process. The release also addressed elevation of privilege flaws across Desktop Window Manager, WinSock, TDI Translation Driver, Windows Push Notifications, Function Discovery Service, WSUS, Remote Desktop Licensing, Azure Monitor Agent, and Windows kernel components; security feature bypasses in Windows Hello, PowerShell, BitLocker, and Windows Shell; information disclosure bugs in Windows GDI, Print Spooler, Web Account Manager, UPnP Device Host, and the Windows kernel; and denial-of-service issues in .NET/Visual Studio and Windows RDBSS. Cumulative updates for Windows Server 2022 and 23H2 bundled security hardening for Kerberos, RDP, Secure Boot, and WDS, with Microsoft warning that Secure Boot certificates begin expiring in June 2026.
