CVE-2026-47050 in VM VirtualBox
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.8. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks require human interaction from a person other than the attacker and 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 creation, deletion or modification access to critical data or all Oracle VM VirtualBox accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox. CVSS 3.1 Base Score 7.4 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:C/C:N/I:H/A:H).

This vulnerability resides within Oracle VM VirtualBox's core component and affects version 7.2.8, representing a significant security weakness that can be exploited by attackers with high privileges who already have access to the system infrastructure hosting the virtualization environment. The flaw demonstrates characteristics of an easily exploitable vulnerability that requires minimal technical effort from an attacker who has already established a foothold through legitimate credentials or system access. The CVSS 3.1 base score of 7.4 indicates a serious threat level with both integrity and availability impacts rated as high, suggesting that successful exploitation could lead to substantial data compromise and service disruption.
The vulnerability's operational impact extends beyond the immediate VirtualBox environment and can affect additional products through scope change, indicating that attackers may be able to leverage this weakness to compromise other systems or applications within the broader infrastructure. This characteristic aligns with common attack patterns where initial access points are used as launching pads for broader system penetration. The requirement for human interaction from someone other than the attacker suggests that social engineering elements or user-specific actions might be necessary to complete the exploitation process, though this does not reduce the overall threat level significantly.
From a technical perspective, the vulnerability allows unauthorized modification of critical data and provides access to all data accessible through Oracle VM VirtualBox, potentially enabling attackers to manipulate virtual machine configurations, access sensitive guest operating system data, or modify virtual disk images. The capability to cause complete denial of service through hangs or frequently repeatable crashes represents a particularly dangerous aspect as it can render the entire virtualization environment unusable, effectively disabling critical business operations that depend on virtualized infrastructure.
The security implications of this vulnerability align with CWE categories related to privilege escalation and data integrity compromise, where attackers can gain elevated access rights within the virtualization layer. The attack vector AV:L indicates local network access is required, while the low attack complexity AC:L suggests minimal technical expertise is needed for exploitation. The high privileges requirement PR:H means that attackers must already have significant system access before attempting to exploit this weakness, though once achieved, the potential impact remains severe.
Organizations should implement immediate mitigations including updating to patched versions of Oracle VM VirtualBox, implementing additional access controls around the virtualization environment, and monitoring for suspicious activities or unauthorized changes to virtual machine configurations. The scope change aspect of this vulnerability suggests that organizations must also evaluate their broader IT infrastructure for related systems that might be affected through indirect attack paths. Network segmentation strategies should be reinforced to limit lateral movement capabilities, and privileged access reviews should be conducted to ensure only necessary personnel have the required system access levels. Regular vulnerability assessments and penetration testing focused on virtualization environments can help identify similar weaknesses before they can be exploited by malicious actors.
