CVSS
- Version: 3.0
- Vector: CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
- Base score: 7
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 2.63%
- Percentile among all scored CVEs: 85
- Score date: 10/19/2026
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).
💥 Public exploits
Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
