CVE Lookup Free
Look up a CVE: description, severity, and whether it is known-exploited.
What it does
Resolves a CVE identifier to its description, CVSS severity and — critically — whether CISA lists it as known-exploited.
When to use it
- A scanner reported a CVE and you need to know if it is theoretical or actively exploited.
