03 Exploitation and scoring

Exploitation

EPSS probability
36.40% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 98.3% of scored records. A rank, not a probability.
NVD base score
9.8 (CVSS v3.x), scored by the NVD independently of the CNA.
