CVE-2026-87273 is an easily exploitable vulnerability in the Core component of Oracle VM VirtualBox affecting supported version 7.2.16. The vulnerability allows an attacker with local logon access to the infrastructure running VirtualBox, but without VirtualBox privileges, to compromise the product when a separate user performs required interaction. Oracle classifies the issue with a changed scope, meaning successful exploitation may significantly affect additional products or components beyond the vulnerable VirtualBox security authority.
