- SSVC decision
- Not assessed by CISA
- EPSS probability
- 0.76% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 55.0% of scored records. A rank, not a probability.
- NVD base score
- 4.6 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L
- NVD analysis status
- Modified. NVD last modified this record on 2026-06-17.
