- Not assessed by CISA
- EPSS probability
- 3.26% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 87.9% of scored records. A rank, not a probability.
- NVD base score
- 10.0 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
