- Not assessed by CISA
- EPSS probability
- 9.37% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 95.3% of scored records. A rank, not a probability.

- 8.8 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
