SSVC decision: Not assessed by CISA
EPSS probability: 1.40% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 72.3% of scored records. A rank, not a probability.

NVD CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
NVD analysis status: Modified. NVD last modified this record on 2026-06-17.
