Answer in brief
CVE-2020-1350 records a High severity vulnerability in CVE Program Container. The current sources mark it as known exploited. The current feed maps Microsoft/Windows Server (generic), Microsoft/Windows Server, version 1903 (Server Core installation) (generic), Microsoft/Windows Server, version 1909 (Server Core installation) (generic), Microsoft/Windows Server, version 2004 (Server Core installation) (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.
