CNA vs NVD score

NVD: —
CNA · microsoft: 8.1; NVD has not scored this yet; the score shown is the CNA’s.

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N/E:F/RL:O/RC:C

The score given by the assigning authority versus NVD’s independent score. A gap means the severity is contested.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Feb 13, 2024. That signals real attacks, not theory.

Remediation deadline for government agencies: Mar 5, 2024.

Known to be used in ransomware campaigns.
