Microsoft Discloses Windows File Explorer and NTFS Elevation of Privilege Flaws

Microsoft published security advisories for two Windows elevation of privilege vulnerabilities affecting core operating system components: Windows File Explorer (CVE-2025-62565) and Windows NTFS (CVE-2025-55335). The flaws were listed in the Microsoft Security Update Guide as separate issues impacting widely deployed Windows functionality tied to file browsing and the NTFS file system.

The advisories provide limited public technical detail, but both issues could allow an attacker with existing access to a vulnerable system to gain higher privileges. Because the affected components are integral to Windows operations, organizations should review Microsoft’s update guidance for the relevant CVEs, prioritize patch deployment across supported Windows assets, and monitor for follow-on research or exploit activity that could increase operational risk.
