Authenticated code execution via MSMQ type confusion
Published Aug 12, 2025 · Updated Feb 26, 2026
Type confusion in Microsoft Windows Message Queuing allows remote authenticated users to execute code by sending network messages. The MSMQ message-processing path accesses a resource using an incompatible type while handling attacker-controlled message data; Microsoft has not disclosed a narrower function or object. MSMQ must be installed and network-accessible, and the attacker must hold valid credentials; successful exploitation runs code on the affected host.

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.
- Affected versionversion=10.0.10240.0 <10.0.10240.21100
