Senserva AI Opinion for CVE-2025-53728

This is a second information disclosure bug in on premises Dynamics 365 version 9.1 from the same cycle as the one earlier in this list, again Medium severity with a 1 percent EPSS score. Like its sibling, it only matters to organizations still running Dynamics on their own infrastructure rather than the cloud service.

Do this: Apply both Dynamics 365 9.1 on premises fixes together if any such deployment still exists in the environment.
