SSVC decision
Not assessed by CISA
EPSS probability
8.58% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 94.5% of scored records. A rank, not a probability.
NVD base score
9.8 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
