About this tag
The Windows RCE tag covers remote code execution vulnerabilities in various Windows components, including the Performance Monitor, HTTP.sys, Active Directory Domain Services, Microsoft Message Queuing (MSMQ), and Hyper-V. These vulnerabilities, disclosed in 2026, affect Windows 11, Windows Server 2022, and Windows Server 2025. Discussions emphasize patch prioritization, the importance of treating RCE flaws in trusted Windows surfaces seriously, and the challenge of triaging vulnerabilities with sparse public details. Common themes include the need for disciplined patching, understanding the attack surface of legacy services like MSMQ, and interpreting Microsoft's confidence metrics for bugs in virtualization and networking stacks.
