- Not assessed by CISA
- EPSS probability
- 0.56% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 46.7% 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 2026-06-16.
