SSVC decision: Not assessed by CISA
EPSS probability: 0.39% probability of exploitation activity in the next 30 days.
EPSS percentile: Ranks above 31.8% of scored records. A rank, not a probability.
NVD base score: 8.8 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
NVD analysis status: Analyzed. NVD last modified this record on 2026-06-17.
