Answer in brief
CVE-2021-36380 records a High severity vulnerability in CISA ADP Vulnrichment. The current sources mark it as known exploited. The current feed maps n/a/n/a (generic), sunhillo/sureline (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.
