- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.
- EPSS probability
- 0.18% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 7.6% of scored records. A rank, not a probability.
- NVD base score
- 8.8 (CVSS v4.0), scored by the NVD independently of the CNA.
