CVE-2026-20967Network attack vector

Authenticated network privilege escalation

Published Mar 10, 2026 · Updated Mar 10, 2026

Improper input validation in Microsoft System Center Operations Manager 2019, 2022, and 2025 allows remote authenticated users to elevate privileges. Microsoft has not published the affected component, rejected input, or validation operation that mishandles it. Low-privileged access to a network-reachable deployment is required, and successful exploitation grants elevated privileges.
