SSVC decision: Not assessed by CISA
EPSS probability: 0.15% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 4.3% of scored records. A rank, not a probability.

NVD CVSS vector: No NVD score to derive
NVD analysis status: Received. NVD last modified this record on 2026-10-21.
