The report confidence metric is part of which CVSS v3.0 metrics group?

The “Report Confidence” metric is part of the Temporal metric group in the Common Vulnerability Scoring System (CVSS) version 3.0.

The Temporal metric group in CVSS v3.0 includes metrics that can change over time but are not dependent on a particular user’s environment. Along with Report Confidence, this group also includes:

• Exploit Code Maturity: This metric measures the likelihood of the vulnerability being attacked based on the current state of exploit techniques or code availability.
• Remediation Level: This measures the level of available fixes or workarounds for the vulnerability.

The Temporal metrics allow for a more dynamic understanding of the vulnerability as it evolves.
