CVSS

Version: 3.1
Vector: CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Base score: 7.4

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.11%
Percentile among all scored CVEs: 1
Score date: 10/5/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
