CVSS v3 base metrics

Attack vector:More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity:More severe for the least complex attacks.
Privileges required:More severe if no privileges are required.
User interaction:More severe when no user interaction is required.
Scope:More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality:More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity:More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability:More severe when the loss of impacted component availability is highest.
