Local privilege escalation
Published Feb 13, 2024 · Updated Aug 10, 2026
Improper input validation in Microsoft Defender for Endpoint for Windows before 10.0.17763.5122 allows local users to elevate privileges. Microsoft identifies the weakness but has not published the affected code path, untrusted input, or failed validation operation. Exploitation requires low-privileged local access and grants elevated control over the endpoint without user interaction.
