Answer in brief
CVE-2018-8405 records a High severity vulnerability in CVE Program Container. The current sources mark it as known exploited. The current feed maps Microsoft/Windows 10 (generic), Microsoft/Windows 10 Servers (generic), Microsoft/Windows 8.1 (generic), Microsoft/Windows RT 8.1 (generic) and additional mapped packages. 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.
