api-uk.securitycenter.microsoft.com - Vulnerability dates missing

Hi.

We've started to see the following fields with inacurate data (red text below) coming via the Defender API.

Response:

{

"@odata.context": "https://api-uk.securitycenter.microsoft.com/api/$metadata#PublicVulnerabilityDto",

"@odata.count": 97,

"value": [

{

"id": "CVE-2024-43543",

"name": "CVE-2024-43543",

"description": null,

"severity": "Medium",

"cvssV3": 0.0,

"cvssVector": null,

"exposedMachines": 1,

"publishedOn": "0001-01-01T00:00:00Z",

"updatedOn": "0001-01-01T00:00:00Z",

"firstDetected": "2024-10-17T09:14:19Z",

"publicExploit": false,

"exploitVerified": false,

"exploitInKit": false,

"exploitTypes": [],

"exploitUris": [],

"cveSupportability": null,

"tags": [

"PartiallyPatchable"

"epss": null

}, **** single object extracted.

The data appears to display in the portal without issue as you can see below:

Has anyone else using the Defender API seen this on their environment at all?

Cheers.

Nigel
