CVE-2020-0910
Status: ModifiedHigh (8.4)—💥 PoC
A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system, aka 'Windows Hyper-V Remote Code Execution Vulnerability'.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
- Base score: 8.4
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 9.25%
- Percentile among all scored CVEs: 95
- Score date: 10/17/2026
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.
