• AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
• Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.

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.

0.75% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 54.7% of scored records. A rank, not a probability.
