CVE-2026-35247

Cross-scope data disclosure via undisclosed Core flaw

Published Apr 21, 2026 · Updated Apr 21, 2026

Improper access control in Oracle VM VirtualBox 7.2.6 Core allows local users with high privileges to read all accessible data. Oracle identifies the affected locus only as Core and has not published the operation that mishandles access-control decisions or untrusted input. Exploitation requires a high-privilege logon to the host infrastructure and can cross the VirtualBox security scope, but it does not alter data or interrupt service.
