CVE-2026-47043 in VirtualBox
Summary
by MITRE • 07/21/2026
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.12. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle VM VirtualBox accessible data. CVSS 3.1 Base Score 3.2 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N).

This vulnerability exists within Oracle VM VirtualBox version 7.2.12, specifically in the Core component of the Oracle Virtualization suite. The flaw represents a significant security concern as it can be exploited by attackers who already possess legitimate login credentials to the host infrastructure where VirtualBox operates. The vulnerability's exploitability is classified as easily accessible, meaning that an attacker with high-privileged access to the system can leverage this weakness to compromise the virtualization environment itself.
The technical nature of this vulnerability stems from insufficient access controls or improper privilege management within VirtualBox's core functionality. As a local privilege escalation issue, it requires an attacker to first establish a foothold on the host system through legitimate credentials, then utilize this vulnerability to potentially expand their control over the virtualization platform. The CVSS 3.1 score of 3.2 indicates a low severity classification for confidentiality impacts, yet the scope change aspect suggests that successful exploitation could affect additional products beyond just VirtualBox itself.
The operational impact of this vulnerability extends beyond traditional virtualization boundaries, as the compromise of VirtualBox can potentially lead to broader system infiltration due to its central role in hosting virtual machines. The unauthorized read access to a subset of VirtualBox accessible data represents a confidentiality breach that could expose sensitive information stored within or managed by the virtual environment. This type of vulnerability aligns with CWE-284, which addresses improper access control issues, and may also connect to ATT&CK technique T1078 for valid accounts and privilege escalation tactics.
The attack vector analysis reveals that this vulnerability requires local access with high privileges, making it less likely to be exploited remotely but still dangerous in environments where attackers have already gained system-level access. The scope change component indicates that the impact may extend beyond VirtualBox's immediate boundaries, potentially affecting other systems or applications that interact with or depend on the compromised virtualization environment. Organizations should consider implementing additional monitoring and access control measures around their VirtualBox installations, particularly focusing on limiting local administrative privileges and establishing robust network segmentation to prevent lateral movement if such an attack occurs.
Mitigation strategies should include immediate patching of affected Oracle VM VirtualBox instances to version 7.2.13 or later, which would address the identified privilege escalation vulnerability. System administrators should also implement principle of least privilege controls, ensuring that only authorized personnel have high-privileged access to host systems running VirtualBox. Network segmentation and monitoring solutions should be deployed to detect unusual activities around virtualization infrastructure, while regular security assessments should evaluate the overall security posture of virtual environments and their integration with broader enterprise systems.
