Published Sep 15, 2026 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.16. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks of this vulnerability can result in takeover of Oracle VM VirtualBox. Note: This vulnerability applies to Windows host only. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

Analysis

Technical impact

This vulnerability in Oracle VM VirtualBox 7.2.16 allows a low‑privileged attacker that has logged onto the Windows host to take full control of the VirtualBox process, resulting in a compromise of the virtualization platform. The impact includes loss of confidentiality, integrity, and availability of all virtual machines, stemming from an improper access control flaw in the core component.

Affected Systems

Oracle Corporation’s Oracle VM VirtualBox version 7.2.16 on Windows hosts.

Risk and Exploitability

The CVSS 3.1 base score is 7.8, while the EPSS score of 0.00127 indicates a very low probability of exploitation, and the vulnerability is not listed in the CISA KEV catalog. The attack vector is local and requires the attacker to have a user account on the Windows host. Successful exploitation leads to full takeover of VirtualBox without user interaction. Even with a low exploitation likelihood, the potential impact remains high, so the overall risk is considered moderate to high for systems running the affected version, especially where local users have elevated privileges.
