CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
Base score: 10

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 12%
Percentile among all scored CVEs: 96
Score date: 10/12/2026

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.
