- 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
- 0.56% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 44.3% of scored records. A rank, not a probability.
