SSVC decision: Not assessed by CISA
EPSS probability: 0.78% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 55.9% of scored records. A rank, not a probability.
NVD base score: 7.1 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
NVD analysis status: Modified. NVD last modified this record on 2026-09-14.
