Known Exploited Vulnerabilities

Focus on What Matters

There are 303,381 vulnerabilities in the CVE database.
Whilst only 0.7% are ever actively exploited.

This list contains the vulnerabilities that are actively exploited by malware and threat actors that you should prioritize first.

This table displays known exploited vulnerabilities (KEVs) that have been cataloged from over 60 public sources, including CISA, and our own private sensors. Each entry links to a CVE identifier, where the CVE details are enriched with EPSS scores, online mentions, scanner inclusion, exploitation, tags, and other metadata. The goal is to be an early warning system, even before being published by CISA. More data and features coming soon!
