According to the common vulnerability scoring system, which term is associated with scoring multiple vulnerabilities that are exploit in the course of a single attack?

Chained score is not a defined or recognized term within the CVSS specification.

Risk analysis is a broader process of identifying and evaluating risks, not a CVSS-specific term for combining exploits.

Vulnerability chaining is a recognized CVSS concept where an attacker leverages multiple vulnerabilities in combination during a single attack path, with one vulnerability enabling the privilege or access needed to exploit the next. The CVSS specification provides guidance on how to handle scoring when vulnerabilities are chained together in this manner.

Confidentiality is one of the three CIA triad impact metrics used in CVSS scoring, not a term describing the chaining of multiple exploits.
