Local privilege escalation via untrusted data deserialization
Published Apr 14, 2026 · Updated Apr 14, 2026
Deserialization of untrusted data in Microsoft Azure Monitor Agent before 1.41.0 allows local users to elevate privileges. Microsoft has not published the deserialization locus, serialized data format, or unsafe operation that processes attacker-controlled input. Exploitation requires existing low-privileged local access and no user interaction; the resulting elevated privilege level is undisclosed.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
