03 Exploitation and scoring
SRC: CISA, FIRST, NVD, RED HAT- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision

- 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
- 0.36% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 29.2% of scored records. A rank, not a probability.
