GitHub security advisories support CVSS 4.0

GitHub security advisories now support the new CVSS 4.0 schema. CVSS, or the Common Vulnerability Scoring System, is an industry standard maintained by FIRST. The CVSS 4.0 standard adds new metrics for a more thorough assessment of the risk of a particular vulnerability.

When creating a repository security advisory, you can now calculate either a CVSS 4.0 or 3.1 base score and view this data on the published global advisory, related Dependabot alerts, and through the API.
