0.21% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 11.6% of scored records. A rank, not a probability.
NVD base score
4.4 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector
CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
