About CVE Identifiers
CVE Identifiers Defined
CVE Identifiers (also referred to by the community as "CVE names," "CVE IDs," "CVE numbers," "CVE entries," and "CVEs") are unique, common identifiers for publicly known cyber security vulnerabilities.
Each CVE Identifier includes the following:
- CVE Identifier number with four or more digits in the sequence number portion of the ID (e.g., "CVE-1999-0067", "CVE-2014-12345", "CVE-2016-7654321").
- Brief description of the security vulnerability or exposure.
- Any pertinent references (i.e., vulnerability reports and advisories).

Creation of a CVE Identifier
The process of creating a CVE Identifier begins with the discovery of a potential security vulnerability or exposure. The information is then assigned a CVE Identifier by a CVE Numbering Authority (CNA), and posted on the CVE website by the CVE Editor. As part of its management of CVE, The MITRE Corporation functions as CVE Editor and Primary CNA. The CVE Editorial Board oversees this process.
The documents below explain CVE Identifiers and the creation of identifiers in more detail:
Lists the numerous organizations currently participating as CVE Numbering Authorities (CNAs). Includes an introduction to the candidate reservation process; defines CNAs and provides the requirements for being a CNA, describes CNA tasks, and explains the communication requirements from the CNA to MITRE; defines the role of vendor liaisons, and explains the researcher's responsibilities in the process.
The CVE ID Syntax Change took effect on January 1, 2014. CVE IDs using the new numbering format were first issued beginning on January 13, 2015. CVE IDs with 7 digits are actively being assigned by the DWF CNA as of May 24, 2016. This page is a central location of information about, and related to, the syntax change including the following: CVE ID Syntax Compliance, CVE ID Syntax Guidance, and CVE ID Syntax Test Data.
A description of the process of how CVE Identifiers are added to the CVE List, including the roles of CVE Numbering Authorities (CNA) and the CVE Content Team.
CVE Editorial Policies, also Content Decisions (CDs), are the guidelines the CVE Content Team uses to ensure that CVE Identifiers are created in a consistent fashion, independent of who is doing the creation. This page is a central location of information about, and related to, CDs including the following: Editorial Policies Overview; CVE Abstraction Content Decisions: Rationale and Application; and Handling Duplicate Public CVE Identifiers.

Each CVE Identifier includes appropriate references. Each reference used in CVE (1) identifies the source, (2) includes a well-defined identifier to facilitate searching on a source's website, and (3) notes the associated CVE Identifier. CVE also includes a Reference Maps page with links to documents from the commonly used information sources that are used as references for CVE Identifiers.
This page provides a list of the products covered by all CVE Numbering Authorities (CNAs), including MITRE as Primary CNA. A list of the sources used by MITRE-only to assign CVE IDs as the Primary CNA is also included.
This page provides an archive list of the organizations from the information security community that provided us with vulnerability information that helped MITRE create new CVE Identifiers from 1999 through November 2013.
This page provides an archive of the old CVE versions, the last of which was issued in 2006. As new CVE Identifiers are now added to the CVE website on a daily basis and are immediately usable by the community, the most current version of CVE is on the CVE List Master Copy page.
FAQs from the Frequently Asked Questions page in the About CVE section also address specific questions about CVE Identifiers.
Requesting CVE Identifiers
To receive a CVE ID for your issue you must contact a CVE Numbering Authority (CNA). See Request a CVE Identifier for details.
