Sources: NIST National Vulnerability Database (descriptions, CVSS, CPE); CISA KEV, ENISA EUVD, CIRCL and VulnCheck (exploitation status, three catalogues counted; CIRCL shown as an aggregator); FIRST EPSS (exploitation probability). Patch window is the gap between CVE publication and the earliest KEV listing, so a negative value means a catalogue called it exploited before it was disclosed. Data refreshes every five hours.
