Authenticated code execution via undisclosed XXE path
Published Aug 8, 2023 · Updated Aug 10, 2026
XXE in Microsoft Dynamics 365 (on-premises) 9.0 before 9.0.47.08 allows remote authenticated users to execute code. Microsoft identifies improper restriction of XML external entities but has not disclosed the parser, XML input path, or unsafe operation that reaches code execution. Exploitation requires low-privileged authentication and user interaction, and successful execution crosses the vulnerable service's security boundary.

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.
