Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated local user session with at minimum standard (low) privileges - remote unauthenticated exploitation is not possible given AV:L/PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.0 (High) score reflects the full C:H/I:H/A:H local impact moderated by AC:H (race condition or specific heap-state requirement) and PR:L (requires an existing authenticated local session). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released security update distributed via Windows Update or WSUS; exact fixed build numbers per Windows edition are listed in the EUVD-2026-73613 data above (e.g., Windows 11 24H2 fixed at 10.0.26100.9445, Windows Server 2025 at 10.0.26100.33438). … Detailed patch versions, workarounds, and compensating controls in full report. |
