CVSS
- Base score
- 9.8
- Version
- 3.1
- Vector
- CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days
- 6.49 %
- Percentile among all scored CVEs
- 94
- Score date
- 10/31/2026
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.
