03 Exploitation and scoring

SRC: CISA, FIRST, NVD, RED HAT

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: 9.14% probability of exploitation activity in the next 30 days.
EPSS percentile: Ranks above 94.9% of scored records. A rank, not a probability.

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