- Not assessed by CISA
- EPSS probability
- 0.79% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 55.9% of scored records. A rank, not a probability.
- NVD base score
- The NVD has published no score for this record
- NVD CVSS vector
