Use after free in Windows Accounts Control allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in Windows Accounts Control exploits a use-after-free (CWE-416) condition, allowing an authorized but low-privileged local attacker to gain full system-level privileges across a wide range of Windows desktop and server versions. The CVSS 7.0 score (AV:L/AC:H/PR:L) reflects that exploitation requires local authenticated access and high attack complexity, consistent with UAF race-condition exploitation. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated local user session on the affected Windows system (PR:L); fully unauthenticated remote exploitation is not possible given AV:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.0 score is driven by the full C:H/I:H/A:H impact triad, which is realistic for a successful UAF privilege escalation that yields arbitrary code execution at an elevated privilege level. … 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 Microsoft's security update for the relevant Windows version as published via Windows Update, WSUS, or Microsoft Update Catalog. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows 10, Windows 11, and Windows Server 2016-2025 systems in your environment and prioritize servers and shared multi-user endpoints for patching. …
