- EPSS probability
- 0.17% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 6.4% of scored records. A rank, not a probability.
- NVD base score
- 5.7 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L
- NVD analysis status
- Modified. NVD last modified this record on 2026-06-17.
