CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  8.2 HIGH
Vector:  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L

Nist CVSS score does not match with CNA score
CNA:  Kubernetes
Base Score:  6.5 MEDIUM
Vector:  CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
