What is CVE?

Also known as: Common Vulnerabilities and Exposures, CVE ID

Definition

A CVE ID is a unique public identifier, such as CVE-2024-12345, for a disclosed security vulnerability, assigned through the CVE Program.

Why it matters

IDs are issued by CVE Numbering Authorities, which include software vendors and security organizations. The ID tells you which flaw people are talking about; severity and exploitation status come from other sources such as CVSS, EPSS and CISA’s KEV catalog.
