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: 17.00% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 96.7% of scored records. A rank, not a probability.
