SSVC decision
Not assessed by CISA
EPSS probability
11.09% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 95.9% of scored records. A rank, not a probability.
NVD base score
5.9 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector
CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
NVD analysis status
