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.

Submitting CVE Entry Information to CVE Team
Please use one of the following two methods to submit CVE Entry information to the CVE Team.
(1) CVE Request Web Form
- The CVE Request web form is the preferred method for submitting CVE Entry information.
- This method supports all three file types: Flat File, CSV file, and JSON.
- NOTE: The form has limits on form field sizes, which may cause problems when submitting multiple CVE ID requests at one time.
- Use this method for both new and updated submissions.
- Visit the CVE Request web form.
- Select “Notify CVE about a publication” and enter your email address.
- Fill in the form.
- NOTE: “Link to the advisory” and “CVE IDs of vulnerabilities to be published” fields are required.
- The assignment information (in Flat File, CSV, or JSON format) should be entered in the “Additional information and CVE ID description updates” field.
- NOTE: Alternatively, you can send the CVE Entry information as a file attachment in a reply to an email message generated by CVE’s ticketing system when the submission has been received.
- Enter the security code.
- Press “Submit Request.”
(2) Git
- This method supports CVE JSON only.
- NOTE: Avoid files with MS-DOS style line endings (CR/LF).
- This method is suited to both new and updated submissions.
