Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.1.10. 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 access to critical data or complete access to all Oracle VM VirtualBox accessible data. CVSS 3.1 Base Score 6.0 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Oracle VM VirtualBox 7.1.10 contains a vulnerability in its Core component that allows a high-privileged local attacker to gain unauthorized access to critical data. The CVSS vector indicates a local attack requiring high privileges (PR:H) with low complexity (AC:L), resulting in high confidentiality impact. The scope change (S:C) indicates attacks can impact additional products beyond VirtualBox itself.

MitigationApply the appropriate Oracle VirtualBox patch when available. Until then, restrict administrative access to VirtualBox host systems to trusted, high-privilege users only, and monitor for unusual VM access patterns.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check if VirtualBox is installed
    Run 'VBoxManage --version' from a command line or terminal. On Windows, also check for C:\Program Files\Oracle\VirtualBox\. On Linux, check /usr/bin/VBoxManage or /opt/VirtualBox/.
    Affected if VirtualBox is not installed on the system
  2. Determine the exact installed version
    Execute 'VBoxManage --version' and note the full version string returned (for example, 7.1.10r123456). The version is displayed in the output before the build number.
    Affected if Command fails or returns no version string
  3. Verify version matches CVE-2025-53026
    Compare the installed version string against 7.1.10. This CVE affects exactly version 7.1.10 (any build variant such as r123456). Check if the version begins with 7.1.10.
    Affected if Installed version is 7.1.10 (any build suffix)
  4. Confirm high-privilege attacker scenario
    This vulnerability requires a high-privileged local attacker. Verify that untrusted users with high privileges (such as administrator or root-level accounts) have access to the VirtualBox host system.
    Affected if Untrusted high-privilege users can access the VirtualBox host

User is affected if VirtualBox version 7.1.10 is installed and untrusted high-privilege local users can access the VirtualBox host system.

Mitigation

Apply the appropriate Oracle VirtualBox patch when available. Until then, restrict administrative access to VirtualBox host systems to trusted, high-privilege users only, and monitor for unusual VM access patterns.

Recommended fix Moderate confidence

VirtualBox 7.1.14 or latest 7.1.x release

  1. 1. Download the latest VirtualBox release from the official Oracle website (https://www.virtualbox.org/wiki/Downloads)
  2. 2. Ensure all running virtual machines are properly shut down before upgrading
  3. 3. Uninstall the current VirtualBox 7.1.10 installation
  4. 4. Install the latest VirtualBox version (7.1.14 or newer recommended)
  5. 5. After installation, verify the installed version matches the expected fixed release
Caveat Upgrade may require reconfiguration of VM settings; ensure backups of VM configurations exist before upgrading
