Microsoft published security advisories for several elevation-of-privilege vulnerabilities affecting Windows components and related software, including Microsoft PC Manager (CVE-2025-21322), Windows Installer (CVE-2025-21331, CVE-2025-21373), Visual Studio (CVE-2025-49739), .NET (CVE-2025-55247), Windows Health and Optimized Experiences (CVE-2025-59241), and Host Process for Windows Tasks (CVE-2025-60710). Microsoft also lists an earlier Windows Storage privilege-escalation issue, CVE-2023-36399, in its security guidance portal.
The advisories provide limited public detail beyond product names and vulnerability class, but the grouping indicates broad exposure across both endpoint and developer environments where successful exploitation could allow an attacker to gain higher privileges on a target system. Organizations using affected Microsoft software should review the corresponding Security Update Guide entries, prioritize patch validation for Windows and developer-tooling assets, and assess whether privilege-escalation paths could be chained with other flaws or post-compromise activity.
