SSVC decision: Not assessed by CISA
EPSS probability: 8.49% probability of exploitation activity in the next 30 days.
EPSS percentile: Equal to or higher than the score of 94.8% of scored records. A rank, not a probability.

NVD CVSS vector: No NVD score to derive
NVD analysis status: Modified. NVD last modified this record on 2026-06-16.
