CVE-2025-53144Network attack vector

Authenticated code execution via MSMQ type confusion

Published Aug 12, 2025 · Updated Feb 26, 2026

Type confusion in Microsoft Message Queuing on affected Windows releases allows remote authenticated users to execute arbitrary code over a network. Microsoft identifies incompatible-type resource access but does not disclose the malformed field, confused types, or responsible function. Low-privileged credentials and network access to an enabled MSMQ service are required; successful exploitation runs code on the target.
