External exposure likelihood

Halo Surface Signal score for CVE-2024-38112

The MSHTML platform is a Windows component, not a standalone internet-facing service. While reachable via network-delivered content in browsers or applications, it is not exposed by design. Direct public-internet reachability is uncommon, as exploitation requires a user to interact with specifically crafted content.
