03 Exploitation and scoring

Exploitation

SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.95% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 61.1% of scored records. A rank, not a probability.
NVD base score
