03 Exploitation and scoring
- Exploitation
- Not assessed. CISA has not published an exploitation assessment for this record, and it is not in the KEV catalog. That is an absence of assessment, not a finding of no risk.
- SSVC decision
- Not assessed by CISA
- EPSS probability
- 3.69% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 89.2% of scored records. A rank, not a probability.
- NVD base score
- The NVD has published no score for this record
- NVD CVSS vector
- No NVD score to derive
- NVD analysis status
- Modified. NVD last modified this record on 2026-06-17.
