The Forum of Incident Response and Security Teams (FIRST) has released CVSS v4.0, the latest version of the Common Vulnerability Scoring System standard. CVSS v4.0 offers improved granularity through new base metrics and values, as well as better impact metrics. It introduces a new nomenclature for severity ratings, including Base (CVSS-B), Base + Threat (CVSS-BT), Base + Environmental (CVSS-BE), and Base + Threat + Environmental (CVSS-BTE). The revised standard aims to provide a consistent way to evaluate vulnerabilities' impact and compare risks across different systems and software. The release of CVSS v4.0 was announced by FIRST during its 35th annual conference in Montreal, Canada. In addition to CVSS, FIRST has also published TLP 2.0, the latest version of its Traffic Light Protocol standard. The release of CVSS v4.0 demonstrates FIRST's commitment to continuously improving cybersecurity and defending against cyberattacks.

The Forum of Incident Response and Security Teams (FIRST) has released CVSS v4.0, the latest version of the Common Vulnerability Scoring System standard. CVSS is a framework used to assess the severity of software security vulnerabilities. It assigns numerical scores or qualitative representations based on exploitability, impact on confidentiality, integrity, availability, and required privileges. The new version provides finer granularity in base metrics, removes scoring ambiguity, simplifies threat metrics, and enhances the assessment of security requirements and compensating controls. It also introduces supplemental metrics for vulnerability assessment and expands applicability to OT/ICS/IoT systems. The release of CVSS 4.0 marks a significant milestone in the evolution of the system, which has been continuously developed over the past 18 years. The complete list of changes in CVSS v4.0 is available on the FIRST website.
CVSS v4.0 offers improved granularity through new base metrics and values, as well as better impact metrics. It introduces a new nomenclature for severity ratings, including Base (CVSS-B), Base + Threat (CVSS-BT), Base + Environmental (CVSS-BE), and Base + Threat + Environmental (CVSS-BTE). The revised standard aims to provide a consistent way to evaluate vulnerabilities' impact and compare risks across different systems and software. It helps prioritize responses to security threats and enhances the assessment of environment-specific security requirements.
The release of CVSS v4.0 was announced by FIRST during its 35th annual conference in Montréal, Canada. Chris Gibson, CEO of FIRST, described it as a "cyber sector game-changer" and highlighted the significant rise in threats worldwide. FIRST is a membership organization dedicated to improving cybersecurity and fostering collaboration among its members to defend against cyberattacks.
In addition to CVSS, FIRST has also published TLP 2.0, the latest version of its Traffic Light Protocol standard used in the computer security incident response team (CSIRT) community for sharing sensitive information.
The release of CVSS v4.0 is a significant development in the field of vulnerability severity rating standards. It provides a more comprehensive and refined framework for assessing software security vulnerabilities. The new version offers improved granularity, removes scoring ambiguity, and enhances the assessment of environment-specific security requirements. It also expands applicability to OT/ICS/IoT systems and introduces supplemental metrics for vulnerability assessment. The release of CVSS v4.0 demonstrates FIRST's commitment to continuously improving cybersecurity and defending against cyberattacks.
