03 Exploitation and scoring

Exploitation: Not assessed. CISA has not published an exploitation assessment for this record, and it is not in the KEV catalog. That is an absence of assessment, not a finding of no risk.
SSVC decision: Not assessed by CISA
EPSS probability: 7.82% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 94.6% of scored records. A rank, not a probability.
NVD base score: 7.3 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
NVD analysis status: Modified. NVD last modified this record on 2026-06-16.
