CVE-2026-71141: 
VirtualBox vulnerability analysis and mitigation

CVE-2026-71141 is a tampering vulnerability in the Core component of Oracle VM VirtualBox affecting version 7.2.14. It allows a local, unauthenticated attacker with logon access to the host infrastructure to compromise VirtualBox through specially crafted interactions that require human interaction from another user. The vulnerability carries a scope change, meaning successful exploitation may impact products beyond VirtualBox itself. It was disclosed and patched on August 18, 2026, as part of Oracle's Critical Security Patch Update (CSPU). It has a CVSS v3.1 base score of 7.7 (High) (Oracle Advisory, NVD).

The vulnerability resides in the Core component of Oracle VM VirtualBox 7.2.14 and is classified as a tampering/integrity vulnerability. The attack vector is local (AV:L), requiring the attacker to have logon access to the infrastructure where VirtualBox executes, but no privileges are required (PR:N). Exploitation requires human interaction from a person other than the attacker (UI:R), suggesting a social engineering or malicious file/interaction scenario. The scope change (S:C) indicates the vulnerability can affect resources beyond the VirtualBox process itself, potentially impacting the host OS or other guest VMs. No specific CWE classification has been assigned by NVD at this time (Oracle Advisory, NVD).

Successful exploitation can result in unauthorized creation, deletion, or modification of critical data accessible by Oracle VM VirtualBox (high integrity impact), unauthorized read access to a subset of VirtualBox-accessible data (low confidentiality impact), and a partial denial of service of VirtualBox (low availability impact). The scope change means the impact may extend beyond the VirtualBox instance itself to other products or resources on the same infrastructure, increasing the risk of lateral movement or host compromise (Oracle Advisory, NVD).

There is no public proof-of-concept exploit code known at this time, and no evidence of in-the-wild exploitation has been reported. The EPSS score is 0.0, indicating a currently low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. The vulnerability was reported to Oracle by Diego Palacios (Oracle Advisory).

Oracle has released a patch for this vulnerability as part of the August 18, 2026 Critical Security Patch Update (CSPU). Users running Oracle VM VirtualBox 7.2.14 should apply the available patch immediately by following the instructions in the Oracle patch availability documentation. As a temporary measure, Oracle recommends restricting logon access to the infrastructure where VirtualBox executes to authorized personnel only, and implementing access controls and monitoring for VirtualBox operations. Oracle strongly advises against relying on workarounds as a long-term solution (Oracle Advisory).
