AnalysisAI

Oracle VM VirtualBox 7.2.14 Core component contains a vulnerability that allows a high-privileged local attacker to breach VM isolation boundaries and access all confidential data accessible to VirtualBox, including data from guest virtual machines. The CVSS scope-change metric (S:C) confirms that successful exploitation extends impact beyond the VirtualBox process itself, enabling unauthorized read access to critical data across VM boundaries. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires: (1) local logon to the physical or virtual infrastructure hosting Oracle VM VirtualBox - remote network exploitation is not possible per AV:L; (2) high-privilege access (PR:H) on the host, consistent with administrator or root-level credentials; (3) Oracle VM VirtualBox version 7.2.14 installed and running. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 base score of 6.0 (Medium) is consistent with the constrained exploitation profile: AV:L limits exposure to actors already on the host, and PR:H further restricts to administrators or root-equivalent users - these are significant barriers. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation	Apply Oracle's August 2026 Critical Security Patch Update, available at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report.
