Low risk2th percentile - higher than 2% of all known CVEs
Summary
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The affected supported version is 7.2.16. An unauthenticated attacker with logon to the infrastructure where VirtualBox executes can exploit a vulnerability requiring human interaction, potentially leading to takeover of Oracle VM VirtualBox and impacting additional products (scope change).
Risk Assessment
Exploitation could allow an attacker to take over VirtualBox and impact additional products, threatening confidentiality, integrity, and availability.
Recommendation
Update Oracle VM VirtualBox to a version newer than 7.2.16 per Oracle guidance. Restrict local access and educate users about interacting with untrusted content.

Original NVD description (English source)
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).
