Scores use the CVSS v3.1 specification equations, including its Roundup function, which rounds up to one decimal using integer arithmetic so that floating point noise cannot push a score up a tenth. Severity: 0.0 None, 0.1 to 3.9 Low, 4.0 to 6.9 Medium, 7.0 to 8.9 High, 9.0 to 10.0 Critical. Temporal and environmental equal the base score until those metrics are set.
