What is a CVE?
A CVE is a public ID for one known security flaw in one piece of software, written like CVE-2024-3400. The ID lets everyone, from the maker to your IT team, talk about the same problem.
Vulnerability search is a free lookup for every published CVE, over 400,000 of them. Type an ID to see how severe a flaw is, whether criminals are using it, how likely it is to be used and what it affects. It’s for anyone who needs a clear answer quickly, with no account.

CVSS rates how bad a flaw could be, from 0 to 10, if someone used it. It describes the flaw in theory. It says nothing about whether anyone is actually using it.
Thousands of flaws score high, and most are never used against anyone. Fixing by severity alone buries the few that criminals are using today. Under 1% of all CVEs reach Critical on our risk score.
Evidence it’s being used in real attacks. Our risk score weighs that first, then severity, exposure and threat activity. Anything confirmed exploited is marked for an emergency patch, whatever its score.
Look up threat groups, industries and software makers too. No account needed.

It covers every published CVE, over 400,000 of them, and we keep watching for new ones. The list on this page shows the most recently published.
A score from 0 to 100 that we keep up to date for every CVE as the evidence changes. Evidence the flaw is being exploited counts most, then how severe it is, then how widely exposed it is and related threat activity. 85 and above is Critical.
