CVE-2026-47061

Vulnerability in the JDBC component of Oracle Database Server. Supported versions that are affected are 19.3-19.31, 21.3-21.22 and 23.4.0-23.26.2. Difficult to exploit vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the JDBC executes to compromise JDBC. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in JDBC, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all JDBC accessible data. CVSS 3.1 Base Score 5.6 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N).
