Oracle VM VirtualBox EUVD-2026-62059

Exploitation requires three concurrent conditions: (1) local logon access to the host infrastructure running Oracle VM VirtualBox - the AV:L vector explicitly excludes remote exploitation; (2) high privileges on that host system (PR:H), meaning the attacker must already hold an elevated or administrative account before exploitation begins; and (3) the ability to satisfy AC:H conditions, indicating a non-trivial exploitation sequence that may depend on system state, timing, or internal configuration of the Core component. No user interaction is required (UI:N). Limiting factors are significant: the combination of local-only attack vector, high privilege requirement, and high attack complexity makes this unsuitable for remote, automated, or unauthenticated exploitation. The CWE is not specified, so the exact internal trigger condition or configuration dependency within the Core component is not confirmed from available data.

The CVSS 3.1 base score of 7.5 with vector AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H presents a nuanced risk profile: the maximum CIA impact and scope change are severe in theory, but AC:H and PR:H substantially constrain practical exploitability, limiting realistic exposure to insider threats and post-compromise escalation scenarios rather than opportunistic remote attack. No EPSS score is included in available intelligence, and the vulnerability is absent from the CISA Known Exploited Vulnerabilities catalog, meaning no empirical exploitation signal is confirmed - risk must be assessed from structural CVSS metrics alone. Even a mid-sized municipal IT team in kalisz running VirtualBox as primary virtualization infrastructure should treat this as a priority patch-cycle item, because a malicious insider or compromised admin account bypasses the PR:H barrier and could achieve full hypervisor takeover affecting all hosted guests. The scope change is the primary escalation factor, as it extends impact beyond VirtualBox itself. The tension between 'full takeover with scope change' and 'local, high-privilege, difficult-to-exploit' means this ranks higher for organizations with shared multi-tenant virtualization hosts and lower for single-user desktop deployments.

An attacker with an existing high-privilege account on the host system - such as a compromised administrator or malicious insider - interacts with the VirtualBox Core component under specific, difficult-to-reproduce conditions on version 7.2.14. After satisfying the AC:H exploitation requirements, the attacker crosses the hypervisor security boundary, achieving full VirtualBox takeover including confidentiality, integrity, and availability impact over hosted guest VMs. No public proof-of-concept code has been identified at time of analysis.
