How the CVE Works:
CVE-2025-50069 is a vulnerability in the Java VM component of Oracle Database Server (versions 19.3-19.27 and 21.3-21.18). An attacker with low privileges (Create Session, Create Procedure) can exploit this flaw via Oracle Net to compromise Java VM. Despite being confined to Java VM, successful exploitation can lead to unauthorized access to critical data within the database, impacting other linked products (scope change). The attack leverages improper access controls, allowing an attacker to bypass security restrictions and retrieve sensitive information. The CVSS 3.1 score of 7.7 (High) reflects its significant confidentiality impact.
