Provide an API to get the CVRF for a single CVE (previously worked in old portal site)

[UberMeatShield]

The old endpoints around the portal api used to provide a nice clean lookup by CVE:
https://portal.msrc.microsoft.com/api/security-guidance/en-us/CVE/

Response: CVRF response in json or xml based on the headers used for the request.
ie: {"Content-Type": "application/json"} would get you back json content

Now the process is really awkward as you have to do something like:
GET https://api.msrc.microsoft.com/cvrf/v2.0/Updates('CVE-2021-28311')

• Given a list of updates, find the latest date based response id: "2021-Mar"

GET https://api.msrc.microsoft.com/cvrf/v2.0/cvrf/2021-Apr

• Parse through that full cvrf file and look for your CVE you want information on

In addition the Updates API doesn't seem to show the latest Update date with the CVE either? CVE-2021-28311 is updated in 2021-Apr but the API response has a last date of March :(
