AnalysisAIv1 – Sep 15, 2026

The user wants a JSON analysis for CVE-2026-87273, Oracle VM VirtualBox Core, CVSS 8.6, AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H.

Let me construct fields carefully.

Product name: "Oracle VM VirtualBox" (3 words... "Oracle VM VirtualBox" - that's 3 words). Good.

Summary: Do not start with "A vulnerability". Start with impact verb + product. Something like: "Oracle VM VirtualBox 7.2.16 contains a Core component flaw that lets an attacker with logon access to the host... trigger memory corruption via a crafted guest/host interaction requiring user interaction, leading to full takeover of the VirtualBox process with scope change affecting additional products."

Technical context: Hypervisor/core component, scope change S:C means the vulnerability in VirtualBox can impact other components (e.g., host OS or other VMs). AV:L means local access — attacker must have logon to infrastructure where VirtualBox executes — that's a common Oracle phrasing for AV:L (local logon, but not necessarily VM guest). CWE not provided, but Oracle typically assigns memory safety / sandbox escape classes. We shouldn't invent CWE. State that CWE was not assigned/provided and the root cause class is inferred from CVSS scope change and impacts — likely a flaw in the Core component enabling escape from intended privilege boundary.

Risk assessment: CVSS 8.6 high, AV:L reduces, AC:L, PR:N but requires logon (authentication requirement nuance — description says "unauthenticated attacker with logon to the infrastructure"). PR:N in vector but "with logon" is ambiguous — Oracle's AV:L/PR:N means the attacker has a local account on the host but no elevated privileges. UI:R — requires victim user interaction. S:C — scope change. EPSS not provided, no KEV, no POC info. State explicitly that EPSS/KEV data absent.

Affected products: Oracle VM VirtualBox 7.2.16 (per Oracle advisory cspusep2026). Note the advisory URL. CPE not provided.

Remediation: patch — Oracle advisories reference fixes in CPUs; version f

DescriptionCVE.org

Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.16. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle VM VirtualBox. CVSS 3.1 Base Score 8.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H).

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
