SSVC decision: Not assessed by CISA
EPSS probability: 0.08% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 0.3% of scored records. A rank, not a probability.

NVD CVSS vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
NVD analysis status: Modified. NVD last modified this record on 2026-10-21.
