Authenticated code execution via insufficiently granular access control
Published Jul 14, 2026 · Updated Jul 14, 2026
Remote code execution in Microsoft Windows Event Logging Service allows remote authenticated users to execute code over a network. The service makes an authorization decision at insufficient granularity, but Microsoft has not disclosed the affected interface or access-control operation. Exploitation requires low-privileged authentication and user interaction, and successful attacks execute attacker-controlled code on the target.

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.
