What Is CVE (Common Vulnerabilities and Exposures)?

CVE stands for Common Vulnerabilities and Exposures. It is a globally recognized standard used to identify and reference known vulnerabilities in software and hardware.

By assigning a unique CVE identifier, organizations and security professionals can communicate clearly and consistently about security issues.

What Is a CVE Identifier?

A CVE identifier follows this format:

CVE-YYYY-NNNNN

For example: CVE-2023-12345

Each identifier refers to one specific vulnerability and includes:

• the year it was registered
• a unique sequential number

CVE entries act as references and do not contain remediation instructions.

What Is CVE Used For?

CVE is widely used in cybersecurity, including for:

• Vulnerability management
• Patch management
• Security monitoring and detection
• Incident response
• Risk assessment and reporting

Most security tools and vulnerability scanners rely on CVE identifiers.

Who Maintains CVE?

The CVE program is maintained by MITRE, together with a global network of CVE Numbering Authorities (CNAs). These organizations are authorized to assign and publish CVEs.

Why Is CVE Important?

Without CVE, vulnerabilities would be named differently by each vendor or researcher. CVE enables:

• Consistent vulnerability tracking
• Improved collaboration
• Faster response to security issues

CVE is a foundational element of modern cybersecurity practices.
