- SSVC decision
- Not assessed by CISA
- EPSS probability
- 2.21% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 82.1% of scored records. A rank, not a probability.

- 7.5 (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:U/C:N/I:N/A:H
