CVSS
- Version: 2.0
- Vector: AV:N/AC:M/Au:N/C:N/I:P/A:P
- Base score: 5.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 14%
- Percentile among all scored CVEs: 96
- Score date: 10/9/2026
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.
