SSVC decision: Not assessed by CISA
EPSS probability: 2.40% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 83.8% of scored records. A rank, not a probability.
NVD base score: 7.5 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
NVD analysis status: Modified. NVD last modified this record on 2026-06-17.
