Answer in brief
CVE-2026-72530 records a High severity (CVSS 9.0) vulnerability in CISA ADP Vulnrichment. The current sources mark it as known exploited. The current feed maps TrueConf/TrueConf Server (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 9.0. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.
