03 Exploitation and scoring

SRC: CISA, FIRST, NVD, RED HAT

SSVC decision: Not assessed by CISA
EPSS probability: 1.27% probability of exploitation activity in the next 30 days.
EPSS percentile: Ranks above 67.7% of scored records. A rank, not a probability.

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