03 Exploitation and scoring

Exploitation
Not assessed. CISA has not published an exploitation assessment for this record, and it is not in the KEV catalog. That is an absence of assessment, not a finding of no risk.
SSVC decision
Not assessed by CISA
EPSS probability
0.46% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 40.0% of scored records. A rank, not a probability.
NVD base score
6.0 (CVSS v4.0), scored by the NVD independently of the CNA.
NVD CVSS vector
