Definition of CVE

Common Vulnerabilities and Exposures (CVE) is a list of publicly disclosed information security vulnerabilities and exposures. Each entry in the CVE database includes an identification number, a description, and at least one public reference. The purpose of CVE is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services) and to provide a standard for assessing the coverage of their security tools and services.

Origin of CVE

CVE was launched in 1999 by MITRE, a not-for-profit organization that operates research and development centers sponsored by the federal government. Its creation was a response to the growing need for a standardized approach to vulnerability and exposure management. The aim was to provide a universal, standardized identifier for known vulnerabilities, making it easier for everyone, from security practitioners to business leaders, to understand and address cybersecurity risks.

Practical Application of CVE

In practice, CVE plays a critical role in various aspects of cybersecurity. It's widely used by cybersecurity professionals to identify and discuss vulnerabilities. Security teams use CVE identifiers when assessing their systems for exposure to known vulnerabilities, while software vendors use them to ensure patches and updates address specific, known issues. Additionally, CVE is crucial in compliance and security auditing, as it provides a common language for discussing vulnerabilities.

Benefits of CVE

The benefits of CVE are significant and diverse. For cybersecurity professionals, it provides a common language to discuss vulnerabilities, simplifying communication and coordination. CVE also supports better security management, as it allows for the quick identification and rectification of vulnerabilities. For businesses and organizations, CVE helps in risk assessment and compliance, ensuring they are aware of and can mitigate known threats. Furthermore, CVE aids in creating more secure systems and software from the outset, as developers can reference it during the development process.


CVE information is available publicly and can be accessed through the CVE website or various security platforms that integrate CVE data.

While CVE entries are technical in nature, they are a valuable resource for anyone responsible for the security of information systems, including non-technical users, by providing a standardized way of discussing and addressing vulnerabilities.

A CVE entry indicates a recognized vulnerability, which could be exploited. However, not all CVE entries represent active threats; they serve as a catalog of potential security risks.
