# ADF Security advisories

Known exploited vulnerabilities (CISA KEV) enriched with daily FIRST EPSS exploit probability. Query by CVE, vendor, product, text, date added, known ransomware use and minimum EPSS. Fields: CVE ID, vendor, product, vulnerability name, summary, CISA required action, KEV date added and due date, known ransomware use, CWEs, EPSS, verification, paid placement.

This repository holds a free sample of 5 records. The full, daily refreshed dataset (1739 records on 2026-10-12) is served by the ADF Agent Data Feed API and MCP server.
