CVE-2026-60160 Overview
CVE-2026-60160 is an information disclosure vulnerability in Oracle VM VirtualBox, specifically within the Core component. The flaw affects supported version 7.2.12. A high-privileged local attacker with logon access to the infrastructure where Oracle VM VirtualBox executes can exploit this vulnerability. Successful exploitation results in unauthorized read access to a subset of Oracle VM VirtualBox accessible data. The vulnerability carries a scope change, meaning attacks may significantly impact additional products beyond VirtualBox itself. The weakness is categorized under [CWE-200] Information Exposure.
Critical Impact
Local high-privileged attackers can read a subset of Oracle VM VirtualBox accessible data, with scope-changing impact on adjacent products.
Affected Products
- Oracle VM VirtualBox 7.2.12
- Oracle Virtualization (Core component)
- Guest and host systems within scope-change boundary

Technical Details for CVE-2026-60160
Vulnerability Analysis
The vulnerability resides in the Core component of Oracle VM VirtualBox 7.2.12. It exposes a subset of data accessible to the VirtualBox process to an attacker who already holds high privileges on the host infrastructure. The scope change designation indicates the vulnerable component and the impacted component are governed by different security authorities. This means information disclosure in the hypervisor can reveal data belonging to guest virtual machines or other hosted resources. The confidentiality impact is limited but crosses trust boundaries between virtualization tenants.
Root Cause
The root cause is classified under [CWE-200] Exposure of Sensitive Information to an Unauthorized Actor. Oracle has not published low-level implementation details in the public advisory. The flaw allows privileged local processes to retrieve VirtualBox-managed data that should remain isolated from the requesting context. Oracle's July 2026 Critical Patch Update advisory tracks the issue and coordinates the fix across supported virtualization products.
Attack Vector
Exploitation requires local access with high privileges on the system running Oracle VM VirtualBox. No user interaction is needed, and attack complexity is low. The attacker must already be authenticated to the host infrastructure, which limits mass exploitation potential. However, in multi-tenant or shared virtualization environments, a privileged operator on one tenant boundary could read data belonging to another. Refer to the Oracle Security Alert July 2026 for authoritative technical guidance.
No public proof-of-concept code has been released for CVE-2026-60160, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2026-60160
Indicators of Compromise
- Unexpected process access to VirtualBox binaries, VBoxSVC, or VBoxHeadless by non-standard administrative accounts
- Anomalous read operations against VirtualBox configuration files under host user profiles
- Elevation of privilege events on hosts running Oracle VM VirtualBox 7.2.12 preceding suspicious file reads
Detection Strategies
- Inventory all hosts running Oracle VM VirtualBox and flag installations at version 7.2.12
- Correlate high-privileged local logon events with subsequent VirtualBox process interactions
- Monitor for scope-crossing data reads between hypervisor context and guest VM artifacts
Monitoring Recommendations
- Enable audit logging for administrator and root sessions on virtualization hosts
- Track command-line usage of VBoxManage and related utilities executed by privileged users
- Aggregate host telemetry into a centralized data lake to baseline normal VirtualBox administrative behavior and alert on deviations
How to Mitigate CVE-2026-60160
Immediate Actions Required
- Apply the fixes documented in the Oracle Security Alert July 2026 Critical Patch Update
- Restrict local logon rights on VirtualBox hosts to a minimal set of trusted administrators
- Audit accounts with high privileges on virtualization infrastructure and remove unnecessary access
Patch Information
Oracle addressed CVE-2026-60160 in the July 2026 Critical Patch Update. Administrators should upgrade Oracle VM VirtualBox from version 7.2.12 to the version specified in Oracle's advisory. Consult the Oracle Security Alert July 2026 for exact patch levels and download locations.
Workarounds
- Limit interactive and remote logon to VirtualBox hosts to a narrow group of vetted administrators
- Segment virtualization hosts on isolated management networks to reduce exposure of privileged interfaces
- Enforce multi-factor authentication for all privileged accounts on hosts running Oracle VM VirtualBox
# Verify installed Oracle VM VirtualBox version
VBoxManage --version
# List local administrators on a Linux host to review privileged access
