Hi !
Yes indeed. The CVRF files will not include all fields in the advisory. For example, the affected product section will not be in the CVRF file. For your reference, this is a representation of the fields that CVRF currently supports:

Regarding the comment about version information. For IOS and IOS-XE the authoritative sources of version information are the OVAL definitions and IOS Software Checker. For the rest of the advisories, unfortunately there's no support for tools and functionality like OVAL or Software checkers for other products. The human-readable advisory is the most up-to-date document for versions.
