03 Exploitation and scoring
SRC: CISA, FIRST, NVD, RED HAT- Exploitation

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
- 0.91% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 57.2% of scored records. A rank, not a probability.
- NVD base score
- 6.5 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
