Oracle VM VirtualBox Shared Folders data access/modification vulnerability

IdentifiersCVE-2026-35275

CVE-2026-35275 is a vulnerability in the Shared Folders component of Oracle VM VirtualBox. Oracle indicates that the supported affected version is VirtualBox 7.2.8. The issue is classified as difficult to exploit and requires a low-privileged attacker with logon access to the infrastructure where Oracle VM VirtualBox executes. Successful exploitation allows compromise of Oracle VM VirtualBox, with scope change indicating that impacts may extend beyond the vulnerable component to additional products or resources accessible through the VirtualBox environment. Based on Oracle's advisory, the primary security impact is unauthorized access to and unauthorized modification of data accessible to Oracle VM VirtualBox. Specific vulnerable functions or root-cause details were not provided in the available content.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in unauthorized creation, deletion, or modification of critical data or all data accessible to Oracle VM VirtualBox, as well as unauthorized access to critical data or complete access to all Oracle VM VirtualBox-accessible data. Oracle rates the issue CVSS 3.1 7.5 with high confidentiality and integrity impact, no availability impact, and scope changed, meaning compromise may significantly affect additional products or resources beyond the vulnerable Shared Folders component.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by limiting local access to systems running Oracle VM VirtualBox, removing unnecessary privileges from users who do not require access to affected packages or VirtualBox functionality, and restricting access paths required for exploitation where operationally feasible. Oracle notes that blocking required protocols or removing access may reduce risk but can break functionality and should be validated in non-production environments; these are not long-term substitutes for patching.

Remediation

Patch, then assume compromise.

Apply the Oracle June 2026 Critical Security Patch Update for Oracle VM VirtualBox and upgrade from affected version 7.2.8 to the vendor-fixed supported release provided by Oracle. Oracle also recommends remaining on actively supported versions so security patches are available.
