CVE-2025-49746Network attack vector

Authenticated privilege escalation

Published Jul 18, 2025 · Updated Feb 26, 2026

Improper authorization in Microsoft Azure Machine Learning allows remote authenticated users to elevate privileges over a network. Microsoft has not disclosed the affected authorization locus or the operation that fails to enforce the caller's assigned permissions. Low-privileged service access is required, and successful exploitation grants elevated control beyond the caller's original scope.
