This is a critical-severity osint alert from Microsoft Threat Intelligence. It covers the affected product family and was flagged for security teams to evaluate.
Am I affected?
Affected technology is listed in the Affected Products section above. If your asset inventory contains any of them, assume in-scope until you can prove otherwise.
How urgent is the response?
