SSVC decision: Not assessed by CISA
EPSS probability: 1.37% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 71.7% of scored records. A rank, not a probability.
NVD base score: 6.1 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
NVD analysis status: Modified. NVD last modified this record on 2026-06-17.
