CVE Numbering Authorities

CVE Numbering Authorities (CNAs) are organizations from around the world that are authorized to assign CVE IDs to vulnerabilities affecting products within their distinct, agreed-upon scope, for inclusion in first-time public announcements of new vulnerabilities. These CVE IDs are provided to researchers, vulnerability disclosers, and information technology vendors.

Participation in this program is voluntary, and the benefits of participation include the ability to publicly disclose a vulnerability with an already assigned CVE ID, the ability to control the disclosure of vulnerability information without pre-publishing, and notification of vulnerabilities in products within a CNA's scope by researchers who request a CVE ID from them.

To review the products covered by each CNA, visit the Request a CVE ID page.
