CVE Numbering Authorities

CVE Numbering Authorities (CNAs) are organizations that are authorized to assign CVEs to vulnerabilities affecting products within their distinct, agreed-upon scope, for inclusion in first-time public announcements of new vulnerabilities. These CVEs 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 CVE Coverage Goals.

Participating CNAs

The 48 organizations below are participating as CNAs as of January 2017:

Primary CNA

Software Vendors

Third-Party Coordinators
