CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
Base score: 5
Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 6.06%
Percentile among all scored CVEs: 93
Score date: 10/11/2026
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.
